Abstract
Mast cells are immune cells of the haematopoietic lineage that are now thought to have multifaceted functions during homeostasis and in various disease states. Furthermore, while mast cells have been known for a long time to contribute to allergic disease in adults, recent studies, mainly in mice, have highlighted their early origins during fetal development and potential for immune functions, including allergic responses, in early life. Our understanding of the imprinting of mast cells by particular tissues of residence and their potential for regulatory interactions with organ systems such as the peripheral immune, nervous and vascular systems is also rapidly evolving. Here, we discuss the origins of mast cells and their diverse and plastic phenotypes that are influenced by tissue residence. We explore how divergent phenotypes and functions might result from both their hard-wired 'nature' defined by their ontogeny and the 'nurture' they receive within specialized tissue microenvironments.

Abstract
The bladder is a major component of the urinary tract, an organ system that expels metabolic waste and excess water, which necessitates proximity to the external environment and its pathogens. It also houses a commensal microbiome. Therefore, its tissue immunity must resist pathogen invasion while maintaining tolerance to commensals. Bacterial infection of the bladder is common, with half of women globally experiencing one or more episodes of cystitis in their lifetime. Despite this, our knowledge of bladder immunity, particularly in humans, is incomplete. Here we consider the current view of tissue immunity in the bladder, with a focus on defense against infection. The urothelium has robust immune functionality, and its defensive capabilities are supported by resident immune cells, including macrophages, dendritic cells, natural killer cells, and γδ T cells. We discuss each in turn and consider why adaptive immune responses are often ineffective in preventing recurrent infection, as well as areas of priority for future research.

Drug-Induced Mast Cell Eradication: A Novel Approach to Treat Mast Cell Activation Disorders? J Allergy Clin Immunol 2022; 149:1866-1874.

Abstract
Mast cell activation is a key event in allergic reactions, other inflammatory states, and mast cell activation syndromes. Mast cell-stabilizing agents, mediator-targeting drugs and drugs interfering with mediator effects are often prescribed in these patients. However, the clinical efficacy of these drugs varies, depending on the numbers of involved mast cells and the underlying pathology. One straightforward approach would be to eradicate the primary target cell. However, to date, no mast cell-eradicating treatment approach has been developed for patients suffering from mast cell activation disorders. Nevertheless, recent data suggest that long-term treatment with agents that effectively inhibit KIT-function results in the virtual eradication of tissue mast cells and a sustained decrease in serum tryptase levels. In many of these patients, mast cell depletion is associated with a substantial improvement in mediator-induced symptoms. In patients with an underlying KIT D816V+ mastocytosis, such mast cell eradication requires an effective inhibitor of KIT D816V, such as avapritinib. However, the use of KIT inhibitors must be balanced against potential side effects. We here discuss mast cell-eradicating strategies in various disease models, the feasibility of this approach, available clinical data, and future prospects for the use of KIT-targeting drugs in mast cell activation disorders.

Genetic Regulation of Tryptase Production and Clinical Impact: Hereditary Alpha Tryptasemia, Mastocytosis and Beyond. Int J Mol Sci 2021; 22:ijms22052458.

Abstract
Tryptase is a serine protease that is predominantly produced by tissue mast cells (MCs) and stored in secretory granules together with other pre-formed mediators. MC activation, degranulation and mediator release contribute to various immunological processes, but also to several specific diseases, such as IgE-dependent allergies and clonal MC disorders. Biologically active tryptase tetramers primarily derive from the two genes TPSB2 (encoding β-tryptase) and TPSAB1 (encoding either α- or β-tryptase). Based on the most common gene copy numbers, three genotypes, 0α:4β, 1α:3β and 2α:2β, were defined as “canonical”. About 4–6% of the general population carry germline TPSAB1-α copy number gains (2α:3β, 3α:2β or more α-extra-copies), resulting in elevated basal serum tryptase levels. This condition has recently been termed hereditary alpha tryptasemia (HαT). Although many carriers of HαT appear to be asymptomatic, a number of more or less specific symptoms have been associated with HαT. Recent studies have revealed a significantly higher HαT prevalence in patients with systemic mastocytosis (SM) and an association with concomitant severe Hymenoptera venom-induced anaphylaxis. Moreover, HαT seems to be more common in idiopathic anaphylaxis and MC activation syndromes (MCAS). Therefore, TPSAB1 genotyping should be included in the diagnostic algorithm in patients with symptomatic SM, severe anaphylaxis or MCAS.

Abstract
Eucalyptus oil has been used since ancient times for its bactericidal, anti-inflammatory, analgesic and sedative effects. In recent years, the action of Eucalyptus oil has been scientifically proven, and there have been reports that Eucalyptus oil suppresses the production of chemokines, cytokines and lipid mediators in basophils, alveolar macrophages and monocytes. Based on this information, we aimed to verify whether Eucalyptus oil can be used for allergic dermatitis, the incidence of which has been increasing among human skin diseases. This effect was verified using a mouse IgE-mediated local allergic model. In conclusion, topical application of Eucalyptus oil suppressed oedema and vascular permeability enhancement due to IgE-mediated allergic on the skin. In addition, we also verified the degranuration of mast cells, which is a part of its action, and examined whether 1,8-cineole, which is the main component of Eucalyptus oil, suppresses the phosphorylation of PLCγ and p38 directly or indirectly. 1,8-cineole was found to suppress degranulation of mast cells.

Abstract
The origin and functions of mast cells (MCs) have been debated since their description by Paul Ehrlich in 1879. MCs have long been considered 'reactive bystanders' and 'amplifiers' in inflammatory processes, allergic reactions, and host responses to infectious diseases. However, knowledge about the origin, phenotypes and functions of MCs has increased substantially over the past 50 years. MCs are now known to be derived from multipotent hematopoietic progenitors, which, through a process of differentiation and maturation, form a unique hematopoietic lineage residing in multiple organs. In particular, MCs are distinguishable from basophils and other hematopoietic cells by their unique phenotype, origin(s), and spectrum of functions, both in innate and adaptive immune responses and in other settings. The concept of a unique MC lineage is further supported by the development of a distinct group of neoplasms, collectively referred to as mastocytosis, in which MC precursors expand as clonal cells. The clinical consequences of the expansion and/or activation of MCs are best established in mastocytosis and in allergic inflammation. However, MCs have also been implicated as important participants in a number of additional pathologic conditions and physiological processes. In this article, we review concepts regarding MC development, factors controlling MC expansion and activation, and some of the fundamental roles MCs may play in both health and disease. We also discuss new concepts for suppressing MC expansion and/or activation using molecularly-targeted drugs.

Abstract
Killer immunoglobulin-like receptor (KIR) 2DL4 (CD158d) was previously thought to be a human NK cell-specific protein. Mast cells are involved in allergic reactions via their KIT-mediated and FcɛRI-mediated responses. We recently detected the expression of KIR2DL4 in human cultured mast cells established from peripheral blood of healthy volunteers (PB-mast), in the human mast cell line LAD2, and in human tissue mast cells. Agonistic antibodies against KIR2DL4 negatively regulate the KIT-mediated and FcɛRI-mediated responses of PB-mast and LAD2 cells. In addition, agonistic antibodies and human leukocyte antigen (HLA)-G, a natural ligand for KIR2DL4, induce the secretion of leukemia inhibitory factor and serine proteases from human mast cells, which have been implicated in pregnancy establishment and cancer metastasis. Therefore, KIR2DL4 stimulation with agonistic antibodies and recombinant HLA-G protein may enhance both processes, in addition to suppressing mast-cell-mediated allergic reactions.

Abstract
Mast cell activation and degranulation can result in the release of various chemical mediators, such as histamine and cytokines, which significantly affect sleep. Mast cells also exist in the central nervous system (CNS). Since up to 50% of histamine contents in the brain are from brain mast cells, mediators from brain mast cells may significantly influence sleep and other behaviors. In this study, we examined potential involvement of brain mast cells in sleep/wake regulations, focusing especially on the histaminergic system, using mast cell deficient (W/Wv) mice. No significant difference was found in the basal amount of sleep/wake between W/Wv mice and their wild-type littermates (WT), although W/Wv mice showed increased EEG delta power and attenuated rebound response after sleep deprivation. Intracerebroventricular injection of compound 48/80, a histamine releaser from mast cells, significantly increased histamine levels in the ventricular region and enhanced wakefulness in WT mice, while it had no effect in W/Wv mice. Injection of H1 antagonists (triprolidine and mepyramine) significantly increased the amounts of slow-wave sleep in WT mice, but not in W/Wv mice. Most strikingly, the food-seeking behavior observed in WT mice during food deprivation was completely abolished in W/Wv mice. W/Wv mice also exhibited higher anxiety and depression levels compared to WT mice. Our findings suggest that histamine released from brain mast cells is wake-promoting, and emphasizes the physiological and pharmacological importance of brain mast cells in the regulation of sleep and fundamental neurobehavior.

Abstract
HYPOTHESIS Intravenous injection of cultured mast cells (MCs) can reconstitute the MC population in MC-deficient mice. We hypothesize that injected culture-derived MCs do not repopulate all tissues equally. BACKGROUND Mast cells are central elements not only in anaphylaxis and allergy but also in immune reactions to bacteria and other pathogens. Their broad involvement in innate immunity requires extensive research in the future. Studies of MC function often use MC-deficient mice to compare with wild-type animals. A very elegant method to prove that the observed changes are due to the lack of MCs is to compare results in wild-type mice, MC-deficient mice, and MC-deficient mice that have been reconstituted with cultured MCs. Reconstitution of the MC population can be achieved by intravenous injection of MCs into MC-deficient mice. Whether the injected MCs repopulate the desired tissues has to be proven before this model is used. Also, the time frame of the reconstitution has to be demonstrated. METHODS Mast cell-deficient mice were injected with bone marrow-derived cultured MCs, and the mucosa of middle ear (MEs), nose, and tracheobronchial system was analyzed for MCs 4, 6, 8, 10, and 20 weeks after injection. RESULTS Reconstitution of the ME mucosa was complete and persistent for more than 20 weeks. Reconstitution failed in nasal mucosa. In bronchial mucosa, reconstitution was incomplete and transient. CONCLUSION This model can be used to investigate effects of MCs in various immune reactions in the ME. Studies should use the time frame 6 to 8 weeks after reconstitution of the MC population. However, the model has limitations for investigations in the respiratory tract.

Abstract
Mast cells are a native composer of connective tissue of the skin dermis and intestinal and respiratory mucosa. Independent lines of accumulated evidence indicate the existence of an intensive bidirectional crosstalk between mast cells and sensory nerves and suggest that mast cells and sensory nerves may be viewed as a functional unit, which could be of crucial importance in neuroimmunological pathways. Mast cells appear to have a property of influencing smooth muscle function via not only such nerve-mast cell effects, but also direct pathways. In bronchial asthma, mast cells infiltrate the airway smooth muscle layer, and interact directly with smooth muscle cells, suggesting pathogenic roles for mast cells in airway obstruction. Current studies on mast cell biology identified a novel adhesion molecule of mast cells, namely cell adhesion molecule-1, CADM1. This molecule is unique, because it serves as not only simple glue but also appears to promote functional communication between nerve and mast cells and between smooth muscle and mast cells.

Abstract
Mast cells are progeny of the multipotential hematopoietic stem cell (MHSC). Mast cell-committed progenitors (MCPs) leave hematopoietic tissues, migrate in peripheral blood, invade to connective or mucosal tissue, proliferate and differentiate to morphologically identifiable mast cells. Phenotype of mast cells (connective tissue-type or mucosal type) is determined by the site of lodgment of MCPs. Most progeny of the multipotential hematopoietic stem cell lose proliferation potential after maturation, but connective tissue-type mast cells (CTMCs) possess appreciable proliferation potential after maturation. Even after functioning by degranulation, CTMCs proliferate and restore the original morphology. The most important cytokine for development and survival of mast cells is KIT ligand, and the KIT receptor tyrosine kinase is expressed through the whole developmental process of mast cells from MHSC to mature mast cells. The loss-of-function mutation of KIT gene results in depletion of mast cells, whereas its gain-of-function mutation causes mast cell tumors. Since mast cells are involved in various disease processes, intervention in development of mast cells might be beneficial to the treatment.

Abstract
Systemic mastocytosis (SM) is characterized by the abnormal growth and accumulation of mast cells (MC) in one or more organs. The interaction between the cytokine stem cell factor (SCF) and its cognate receptor, the c-kit receptor tyrosine kinase (KIT), plays a central role in regulating MC growth and differentiation. Whereas germline and somatically acquired activating mutations of KIT have been identified in SM, the issue as to whether individual KIT mutation(s) are necessary and sufficient to cause MC transformation remains unclear based on currently available data. Activating mutations of platelet-derived growth factor receptor-alpha (FIP1 L1-PDGFRA) are identified in a significant number of SM cases that have associated eosinophilia. To date, as with gastrointestinal stromal tumors, activating mutations of KIT and PDGFRA appear to be alternative and mutually exclusive genetic events in SM. The World Health Organization has specified criteria for classification of SM into six major subtypes: cutaneous mastocytosis, indolent systemic mastocytosis (ISM), systemic mastocytosis with an associated clonal hematological non-mast-cell disorder (SM-AHNMD), aggressive systemic mastocytosis (ASM), mast cell leukemia, and mast cell sarcoma. The ability to molecularly classify individual SM cases based on the presence or absence of specific mutations allows for molecularly targeted therapy in a growing number of cases. Imatinib mesylate therapy might result in complete remission of SM cases with wild-type KIT, certain KIT mutations, such as F522C, or the FIP1L1-PDGFRA fusion gene, but not of D816V-KIT-bearing SM. For the latter, interferon-alpha and 2-CdA are potential first- and second-line therapeutic options. Other drugs under investigation include novel tyrosine kinase inhibitors, as well as NF-kappaB inhibitors, which might display greater selectivity towards D816V-KIT as compared to wild type KIT. The pathogenesis of mastocytosis, its major clinical subtypes, and recent treatment advances are discussed in this chapter.

Abstract
Mast cells are progeny of multipotential hematopoietic stem cells (MHSCs). MHSCs commit to the mast cell lineage in the bone marrow, and the mast cell-committed progenitors leave the bone marrow, migrate in blood, invade connective or mucosal tissue, and then proliferate and differentiate to connective tissue-type or mucosal mast cell. GATA-1, GATA-2, and PU.1 transcription factors seem to be involved i the commitment to mast cells, and MITF, a basic helix-loop-helix leucine zipper-type transcription factor, seems to be involved in the migration, phenotypic expression, and survival of mast cells. KIT ligand (KITL) is the most important cytoline for development of mast cells, and KIT is the receptor of KITL. Tissues of loss-of-function mutants of KIT, KITL, or MITF are deficient in mast cells.

Abstract
OBJECTIVE Establishment of a stable umbilical cord blood CD34(+) (UCB CD34(+)) cell culture system and identification of the cells in the cobblestone area differentiated from UCB CD34(+) long-term culture cells. MATERIALS AND METHODS Human UCB CD34(+) cells were cultured on MS-5 mouse stroma cells in the presence of stem cell factor (SCF), flt-3 ligand (FL), and thrombopoietin (TPO) for 4 to 16 weeks. Cells in the culture medium and in the cobblestone area were collected and characterized by flow cytometry and microscopy. RESULTS CD34(+) cells were stably expanded by culturing on MS-5 stroma cells in the presence of SCF, FL, and TPO for more than 4 months. Cells highly expressing CD117 (c-kit) appeared in the cobblestone area after 2 weeks and stably expanded. Isolation of cells highly expressing CD117 by fluorescence-activated cell sorter (FACS) revealed the cells were tryptase-positive and Fc epsilon receptor 1-negative mast cells. They showed typical mast cell morphology and released histamine upon stimulation by substance P or compound 48/80 in vitro. CONCLUSION Human UCB CD34(+) cells were stably expanded on MS-5 stroma cells in the presence of SCF, FL, and TPO. Under this condition, multipotent CD34(+) cells and mast cells differentiated from UCB CD34(+) cells were expanded in the cobblestone area. The expanded mast cells showed histamine release after substance P or compound 48/80 stimulation. These human mast cells will be useful as a source of human cells for evaluating the allergic effects of drugs.

Abstract
Thalamic mast cells (TMCs), the only immunocytes known to infiltrate the brain in physiological conditions, respond to pharmacological agents including sumatriptan - a serotonergic anti-migraine agent - that increases their number. We analysed the effects of two other main analgesics: morphine chlorhydrate, a micro opioid agonist, and acetylsalicylic acid (ASA), a non-steroidal anti-inflammatory drug. All three drugs have specific modes of action, and morphine and ASA, unlike sumatriptan, are also known to interact with peripheral mast cells. Only ASA was effective in promoting TMC number decrease. TMCs, unlike other mast cells, do not express cyclooxygenase (COX) - the key enzyme in the production of prostanoids and the main site of action of ASA - thus dismissing a direct local cellular COX-mediated action. Direct TMC COX-independent mechanisms or effects mediated via distant populations of COX-positive cells such as platelets, leptomeningeal, endothelial and peripheral mast cells are thus probable. ASA, morphine and sumatriptan have distinct TMC effects, suggesting that the TMC number variations they induce are more likely to derive from systemic vasoactive actions than from pharmacological mechanisms devoted to pain relief.

Abstract
Mast cells are found in the central nervous system (CNS) as well as in the periphery. In the brain of mice, they are localized primarily in the thalamus and meninges. Although their numbers increase in response to stress, the mediator of their recruitment is not known. During studies in which drugs were delivered intrathecally in a volume sufficiently large to distribute to the brain, we discovered that repeated daily injections of this large volume increased the number of mast cells in the thalamus. The increase was not due to changes in electrolyte composition of the cerebrospinal fluid (CSF) as chronically administered artificial CSF produced similar effects. Repeated injections of even small volumes (2 mul) increased mast cells in the medial intralaminar (Med), ventral posterior (VP) and posterior (Po) nuclei. Increasing the volume injected daily to 20 mul increased mast cells in the lateral intralaminar (Lat), laterodorsal (LD), ventrolateral (VL) and lateral geniculate (LG) nuclei and further increased those in the lateral extension of the Po nucleus. Thus, small and large volumes augment distinct populations of mast cells. While stem cell factor (SCF) is abundant in the CNS and is chemotactic to mast cells in the periphery, thalamic mast cells in the rodent do not express c-kit, the SCF receptor, suggesting that this factor may not be responsible for the effect. Consistent with this, centrally injected SCF was incapable of increasing thalamic mast cell populations after either single or chronic (21 days) daily injections compared to the effect of saline alone. Although the mechanism is not known, repeated injections of a large volume of fluid dramatically increase mast cells in the CNS, a phenomenon that may be relevant to clinical conditions of increased CSF pressure or volume.

Abstract
Stem cell factor (SCF), which is well known as a cytokine capable of amplifying development and functions of mast cells, is mainly released from fibroblasts in the peripheral tissue. To investigate whether SCF controlled chemotactic migration of mast cells induced by IgE-specific Ag, murine bone marrow-derived cultured mast cells (BMCMC) and human cord blood-derived cultured mast cells (HuCMC) were preincubated with SCF. Although BMCMC and HuCMC sensitized with IgE directly moved toward specific Ag, preincubation for even 1 h with an optimal dose of SCF suppressed the IgE-mediated chemotactic movement. No or little inhibitory effect of SCF was detected in BMCMC derived from c-kit receptor-defect WBB6F1-W/Wv mice. In contrast, preincubation of BMCMC and HuCMC with SCF enhanced beta-hexosaminidase release and Ca2+ mobilization in response to Ag after sensitization with IgE. Using the real-time record of chemotactic migration, BMCMC preincubated with SCF manifested motionless without degranulation. These results suggest that locally produced SCF may have an inhibitory effect on chemotaxis of mast cells, contributing to their accumulation and enhancement of functions at the peripheral site in allergic and nonallergic conditions.

Abstract
Mutant isoforms of the KIT or PDGF receptors expressed by gastrointestinal stromal tumors (GISTs) are considered the therapeutic targets for STI571 (imatinib mesylate; Gleevec), a specific inhibitor of these tyrosine kinase receptors. Case reports of clinical efficacy of Gleevec in GISTs lacking the typical receptor mutations prompted a search for an alternate mode of action. Here we show that Gleevec can act on host DCs to promote NK cell activation. DC-mediated NK cell activation was triggered in vitro and in vivo by treatment of DCs with Gleevec as well as by a loss-of-function mutation of KIT. Therefore, tumors that are refractory to the antiproliferative effects of Gleevec in vitro responded to Gleevec in vivo in an NK cell-dependent manner. Longitudinal studies of Gleevec-treated GIST patients revealed a therapy-induced increase in IFN-gamma production by NK cells, correlating with an enhanced antitumor response. These data point to a novel mode of antitumor action for Gleevec.

Abstract
Naloxone-induced jumping in morphine-dependent mice is inhibited by cromolyn, a mast cell stabilizer, suggesting that this characteristic withdrawal behavior results from degranulation of mast cells. Because withdrawal is considered as a central phenomenon, degranulation of mast cells located within the CNS may influence aspects of opioid withdrawal. The present study evaluates histologically whether naloxone, injected into opioid dependent mice, induces degranulation of mast cells. Seventy-two hours after the s.c. implantation of a 75 mg morphine pellet, the number and degranulation of thalamic mast cells did not differ from those in placebo-implanted controls. However, two injections of 50 mg/kg of naloxone, 30 and 60 min before tissue collection, increased the number of degranulated mast cells compared to those in mice injected with saline. Analysis throughout the entire thalamus (90 40-micro sections) revealed increases in the total number of mast cells as well as the number that were degranulated, especially in sections 52-60, corresponding to Bregma -2.18 to 2.54. Here, mast cells were clustered in the IGL and VPL/VPM nuclei, and redistributed from the ventromedial to the dorsolateral aspects of the Po and PF nuclei during withdrawal. Degranulation was also greater throughout the LD, LP nuclei during withdrawal. These data reveal a novel neuroimmune reaction to opioid withdrawal in the CNS.

Abstract
Previous studies using mast cell-deficient mice (W/W(v)) revealed that mast cells influence disease onset and severity of experimental allergic/autoimmune encephalomyelitis (EAE), the murine model for multiple sclerosis. The mast cell populations of these mice can be restored by transferring bone marrow-derived mast cells (BMMCs). Studies using the W/W(v) reconstitution model have lead to major advances in our understanding of mast cell roles in vivo. However, despite its common use, details regarding the sites and kinetics of mast cell repopulation have remained largely uncharacterized. In this study, we examined the kinetics and tissue distribution of green fluorescent protein(+) BMMCs in reconstituted W/W(v) mice to identify sites of mast cell influence in EAE. Reconstitution of naive animals with BMMCs does not restore mast cell populations to all organs, notably the brain, spinal cord, lymph nodes, and heart. Despite the absence of mast cells in the CNS, reconstituted mice exhibit an EAE disease course equivalent to that induced in wild-type mice. Mast cells are found adjacent to T cell-rich areas of the spleen and can migrate to the draining lymph node after disease induction. These data reveal that mast cells can act outside the CNS to influence EAE, perhaps by affecting the function of autoreactive lymphocytes.

Abstract
The transplantation of primitive human cells into sublethally irradiated immune-deficient mice is the well-established in vivo system for the investigation of human hematopoietic stem cell function. Although mast cells are the progeny of hematopoietic stem cells, human mast cell development in mice that underwent human hematopoietic stem cell transplantation has not been reported. Here we report on human mast cell development after xenotransplantation of human hematopoietic stem cells into nonobese diabetic severe combined immunodeficient (NOD/SCID)/gamma(c)(null) (NOG) mice with severe combined immunodeficiency and interleukin 2 (IL-2) receptor gamma-chain allelic mutation. Supported by the murine environment, human mast cell clusters developed in mouse dermis, but they required more time than other forms of human cell reconstitution. In lung and gastric tract, mucosal-type mast cells containing tryptase but lacking chymase located on gastric mucosa and in alveoli, whereas connective tissue-type mast cells containing both tryptase and chymase located on gastric submucosa and around major airways, as in the human body. Mast cell development was also observed in lymph nodes, spleen, and peritoneal cavity but not in the peripheral blood. Xenotransplantation of human hematopoietic stem cells into NOG mice can be expected to result in a highly effective model for the investigation of human mast cell development and function in vivo.

Abstract
Mast cell progenitors arise in bone marrow and then migrate to peripheral tissues where they mature. It is presumed that integrin receptors are involved in their migration and homing. In the present study, the expression of various integrin subunits was investigated in three systems of adherent and nonadherent mast cells. Mesentery mast cells, freshly isolated bone marrow-derived mast cells (BMMC) and RBL-2H3 cells grown attached to tissue culture flasks are all adherent mast cells and peritoneal mast cells, and cultured BMMC and RBL-2H3 cells grown in suspension represent nonadherent mast cell populations. Pure populations of mast cells were immunomagnetically isolated from bone marrow, mesentery and peritoneal lavage using the mast cell-specific monoclonal antibody AA4. By immunomicroscopy, we could demonstrate that all of these mast cells expressed alpha 4, alpha 5, alpha 6, beta 1 and beta 7 integrin subunits. The expression of the alpha 4 integrin subunit was 25% higher in freshly isolated mesentery mast cells and BMMC. Consistent with the results obtained by immunomicroscopy, mesentery mast cells expressed 65% more mRNA for the alpha 4 integrin subunit than peritoneal mast cells. In vitro studies were also conducted using the rat mast cell line RBL-2H3. RBL-2H3 cells grown attached to the tissue culture flasks or as suspension cultures expressed the same integrin subunits identified in bone marrow, mesenteric and peritoneal mast cells ex vivo. Similarly, the expression of alpha 4 integrin was higher in adherent cells. Therefore, alpha 4 integrins may play a critical role in the anchorage of mast cells to the extracellular matrix in bone marrow and in peripheral tissues.

Abstract
Mast cells (MCs) are centrally important in allergic inflammation of the airways, as well as in the intestinal immune response to helminth infection. A single lineage of bone marrow (BM)-derived progenitors emigrates from the circulation and matures into phenotypically distinct MCs in different tissues. Because the mechanisms of MC progenitor (MCp) homing to peripheral tissues have not been evaluated, we used limiting dilution analysis to measure the concentration of MCp in various tissues of mice deficient for candidate homing molecules. MCp were almost completely absent in the small intestine but were present in the lung, spleen, BM, and large intestine of beta7 integrin-deficient mice (on the C57BL/6 background), indicating that a beta7 integrin is critical for homing of these cells to the small intestine. MCp concentrations were not altered in the tissues of mice deficient in the alphaE integrin (CD103), the beta2 integrin (CD18), or the recombination activating gene (RAG)-2 gene either alone or in combination with the interleukin (IL)-receptor common gamma chain. Therefore, it is the alpha4beta7 integrin and not the alphaEbeta7 integrin that is critical, and lymphocytes and natural killer cells play no role in directing MCp migration under basal conditions. When MCp in BALB/c mice were eliminated with sublethal doses of gamma-radiation and then reconstituted with syngeneic BM, the administration of anti-alpha4beta7 integrin, anti-alpha4 integrin, anti-beta7 integrin, or anti-MAdCAM-1 monoclonal antibodies (mAbs) blocked the recovery of MCp in the small intestine. The blocking mAbs could be administered as late as 4 d after BM reconstitution with optimal inhibition, implying that the MCp must arise first in the BM, circulate in the vasculature, and then translocate into the intestine. Inasmuch as MCp are preserved in the lungs of beta7 integrin-deficient and anti-alpha4beta7 integrin-treated mice but not in the small intestine, alpha4beta7 integrin is critical for tissue specific extravasation for localization of MCp in the small intestine, but not the lungs.

Abstract
BACKGROUND It remains unclear whether the number of circulating mast cell progenitors is increased in patients with atopic diseases. Distinct genotypes are reported to affect mast cell/basophil activation. OBJECTIVE We compared the number and function of mast cell progenitors present in the peripheral blood from donors with normal IgE (IgE < 400 U/mL) and those with atopic dermatitis accompanied by high serum IgE (IgE > 5000 U/mL). METHODS Purified peripheral blood cells were cultured in serum-free methylcellulose containing stem cell factor (SCF), IL-6 plus IL-3. Fresh methylcellulose containing the cytokines was layered over every 2 weeks. The cultured mast cells were retrieved from the methylcellulose and were functionally analysed. RESULTS Mast cell colonies were distinguished at 6 weeks of culture as other colony types had been degenerated. The number of mast cell colony-forming cells varied depending on donors and was not significantly increased in peripheral blood from the hyper-IgE atopic patients. A significant inversed correlation was found between the number of mast cells per one colony and the ages of donors. The cultured mast cells derived from atopic patients and those from normal IgE donors equally expressed Fc epsilon RI and released histamine through Fc epsilon RI, although IL-4 priming in vitro markedly enhanced the function of mast cells regardless of donors. CONCLUSIONS These results indicate that the number of circulating mast cell progenitors may be regulated by unknown individual factors unrelated to IgE levels. Mast cell function may be regulated largely by environmental factors, such as IL-4, but not determined by their progenitors' genotypes.

Abstract
Loss-of-function mutations of the c-kit receptor tyrosine kinase (KIT) result in depletion of mast cells and interstitial cells of Cajal (ICCs). In contrast, gain-of-function mutations of KIT induce neoplasms of mast cells and ICCs. In humans, the sites of mutations are different between mast cell neoplasms and those of ICCs. The former were found in the juxtamembrane domain between the transmembrane and tyrosine kinase domains, and the latter in the tyrosine kinase domain. Moreover, the mechanism of constitutive activation is different. Point mutations and/or deletions in the juxtamembrane domain induced the KIT dimerization, and the dimerized KIT was activated. A point mutation at the particular aspartic acid in the tyrosine kinase domain induced spontaneous activation without forming dimers. Mutations of the c-kit gene are a good model for understanding the relationship between mutations and diseases in both humans and mice.

Abstract
BACKGROUND Mature human mast cells express several types of adhesion molecules on their surface. Interactions between extracellular matrix (ECM) and adhesion molecules may be important for the migration and localization of mast cells and their precursors in tissues. Little is known about the regulation of adhesion molecules on mast cells during their differentiation. OBJECTIVES To clarify the evolution of adhesion phenotype and function, we examined the expression of adhesion molecules during cultured human mast cell (CHMC) differentiation and tested adhesion of mature CHMCs to various ECM proteins. METHODS CHMCs were obtained by culturing human cord blood-derived CD34(+) cells in the presence of stem cell factor and IL-6. Indirect immunofluorescence and flow cytometry was used to study cell surface expression of adhesion molecules and other markers. Mature CHMCs were tested for adhesion molecule function with immobilized matrix proteins. RESULTS At 1 week of culture, cells expressed CD11a, CD18, CD29, CD49d, and CD49e. At 14 weeks of culture, more mature CHMCs expressed CD11b, CD11c, CD29, CD49b, CD49c, CD49d, CD49e, CD51, CD61, and CD54 and weakly expressed CD18 and CD11a. CD11c, CD51, and CD61 appeared de novo by 4 weeks of culture, whereas CD49b and CD49c appeared by 8 weeks. CD29 decreased at 4 weeks but returned to the identical levels of 1-week-old cells by 8 weeks. Compared with levels at week 1, the levels of CD11a, CD18, CD49d, and CD49e at 4 weeks and beyond decreased during culture. Expression of CD49a, CD49f, and alphad integrin was never detectable during CHMC differentiation. Fourteen-week-old CHMCs significantly adhered to the leucine-aspartic acid-valine-containing connecting segment 1 fragment of fibronectin, the 120-kd argine-glycine-aspartic acid-containing fragment of fibronectin, vitronectin, and laminin through specific integrins. CONCLUSION Expression of integrins and CD54 is differentially regulated during CHMC differentiation, and mature CHMCs can adhere to many ECM proteins. These changes may facilitate emigration from the bone marrow into the circulation and ultimately contribute to the tissue homing and localization pattern seen with mature mast cells.

Matrix Metalloproteinase-9 Production, a Newly Identified Function of Mast Cell Progenitors, Is Downregulated by c-kit Receptor Activation. Blood 1999.

Abstract
Mast cell precursors invade from the peripheral blood into local tissues where they differentiate to their mature phenotypes. However, the mechanism of this migration process has been unclear. We clearly demonstrated here the production and release of matrix metalloproteinase-9 (MMP-9), a matrix-degrading enzyme necessary for leukocyte transmigration, by interleukin-3–dependent mouse mast cell progenitors: bone marrow-derived cultured mast cells and IC-2 mast cells. Because several interleukin-3–independent mast cell lines with active mutations in the c-kit gene did not release MMP-9, the possible involvement of c-kit receptor activation in downregulation of MMP-9 production was predicted. c-kitreceptor activation by stem cell factor led to a significant decrease in MMP-9 production of cultured mast cells and IC-2 mast cells transfected with the c-kit gene. Thus, the present results suggest that mast cell precursors are able to produce MMP-9, which may be essential for mast cell migration into tissues, and that stem cell factor may downregulate the MMP-9 production, resulting in engagement of mast cells to matrix components.

Abstract
Mast cells are found in the brain of many species. Although a considerable body of information is available concerning the development and differentiation of peripheral mast cells, little is known about brain mast cells. In the present study, the ontogeny of mast cells in the dove brain was followed by using three markers: acidic toluidine blue, alcian blue/safranin, and an antiserum to gonadotropin-releasing hormone (GnRH). Mast cells first appear in the pia on embryonic day (E)13-14 in ovo, then along blood vessels extending from the pia into the telencephalon on posthatch day 4-5, and in the medial habenula at week 3. Medial habenular mast cell numbers increase during development, peaking in peripubertal birds, and declining thereafter. Several measures indicate that mast cells mature within the medial habenula: there is an increase in the intensity of metachromasia, a switch from alcian blue granules in young animals to mixed alcian blue and safranin granules in older animals, and an increase in GnRH-like immunoreactivity. These results were extended by using electron microscopy. The architecture of mast cell granules evolved from electron lucent with small electron dense deposits at E15 to more electron dense granules with complex patterns of internal structure by 2 months. Ultrastructural immunocytochemistry for the GnRH-like peptide at 1 month revealed both immunopositive and negative cells, suggesting that the acquisition of this phenotype is not simultaneous across the population. Thus, immature mast cells infiltrate the central nervous system and undergo in situ differentiation within the neuropil.

Abstract
Human mast cells are derived from CD34+ hematopoietic cells present in cord blood, bone marrow, and peripheral blood. However, little is known about the properties of the CD34+ cells. We demonstrated here that mast cell progenitors that have distinct phenotypes from other hematopoietic cell types are present in cord blood by culturing single, sorted CD34+ cells in 96-well plates or unsorted cells in methylcellulose. The CD34+ mast cell-committed progenitors often expressed CD38 and often lacked HLA-DR, whereas CD34+ erythroid progenitors often expressed both CD38 and HLA-DR and CD34+ granulocyte-macrophage progenitors often had CD33 and sometimes expressed CD38. We then cultured single cord blood-derived CD34+CD38+ cells under conditions optimal for mast cells and three types of myeloid cells, ie, basophils, eosinophils, and macrophages. Of 1,200 CD34+CD38+ cells, we were able to detect 13 pure mast cell colonies and 52 pure colonies consisting of either one of these three myeloid cell types. We found 17 colonies consisting of two of the three myeloid cell types, whereas only one colony consisted of mast cells and another cell type. These results indicate that human mast cells develop from progenitors that have unique phenotypes and that committed mast cell progenitors develop from multipotent hematopoietic cells through a pathway distinct from myeloid lineages including basophils, which have many similarities to mast cells.

Abstract
While it is well established that brain mast cells are usually associated with the cerebral vasculature, in ring doves mast cells lie directly in the neuropil of the medial habenula. During normal development mast cells enter the habenula and complete their differentiation in situ. In the present study, we asked what characteristics of the medial habenula contribute to mast cell entry and differentiation. Grafts of embryonic habenula or control optic tectal grafts were placed in the lateral ventricle or anterior chamber of the eye. Transplantation alters the location of the habenula as well as its neural and vascular connections. Three groups of hosts were used for the ventricular grafts: four-month-old and killed three months after transplantation; four-month-old and killed seven months later, and two- to three-year-old gonadectomized males killed three months later. Hosts for the intraocular grafts were four months of age and killed three months later. Mast cells were present in the habenular grafts but not in the control tissue. Mast cells in three- and seven-month-old grafts were phenotypically immature when compared to those of hosts. They contained fewer metachromatic granules, fewer granules immunoreactive to an antiserum against gonadotropin-releasing hormone, and no highly-sulphated proteoglycans. As previously described, gonadectomized adults had fewer mast cells in their medial habenula than did intact animals, but there was no change in mast cell number in habenular grafts. The current experiments indicate that the occurrence and survival of mast cells can occur within the microenvironment of the medial habenula, but that maturation of these cells requires the normal connections of this nucleus. Furthermore, gonadectomy appears to alter mast cell number in the medial habenula by generating a secondary signal which the transplanted tissue is incapable of receiving or processing.

Abstract
Phenotype of P815 mouse mast cells changes markedly during culture in the peritoneal cavity of syngenic BDF1 mice. The cells, cultured for 1 week in the peritoneal cavity of syngenic BDF1 mice, proliferate and express high levels of L-histidine decarboxylase (HDC) and mouse mast cell protease (MMCP)-6 mRNAs, indicating the ability of P815 cells to differentiate toward mature connective tissue mast cells. Peritoneal fluid aspirated from P815-inoculated BDF1 mouse and added to cultured P815 cells in vitro was also found to induce HDC mRNA expression, suggesting that at least some of the humoral factors in the peritoneal fluid induce HDC mRNA transcription. Among the erythroid transcription factors, P815 cells expressed GATA-2 but not GATA-1 mRNA before and after the intraperitoneal incubation. In contrast, the expression of NF-E2 subunit p45 disappeared, while expression of subunit mafK was markedly reduced after incubation. Cotransfection assays using HDC-luciferase reporter and p45 and/or mafK expression constructs showed that NF-E2 affects the transactivation of HDC gene. These results suggest that NF-E2 is also an important transcription factor in mast cell differentiation.

Abstract
The flk2 receptor tyrosine kinase has been implicated in hematopoietic development. Mice deficient in flk2 were generated. Mutants developed into healthy adults with normal mature hematopoietic populations. However, they possessed specific deficiencies in primitive B lymphoid progenitors. Bone marrow transplantation experiments revealed a further deficiency in T cell and myeloid reconstitution by mutant stem cells. Mice deficient for both c-kit and flk2 exhibited a more severe phenotype characterized by large overall decreases in hematopoietic cell numbers, further reductions in the relative frequencies of lymphoid progenitors, and a postnatal lethality. Taken together, the data suggest that flk2 plays a role both in multipotent stem cells and in lymphoid differentiation.

Abstract
Mast cells and basophils are offspring of the multipotential hematopoietic stem cell. Although mast cells sometimes are misunderstood as basophils that have invaded connective or mucosal tissue, these two kinds of basophilic cells are distinguishable by morphology and surface antigenicity. Developmental processes of mast cells and basophils are different. Basophils complete their differentiation within the bone marrow, but precursors of mast cells leave the bone marrow, invade connective or mucosal tissue, proliferate, and differentiate into mast cells. The mechanisms regulating development are different between mast cells and basophils. Both T cell-dependent and fibroblast-dependent mechanisms are involved in the development of rodent mast cells, but only the fibroblast-dependent mechanism is known for development of human mast cells and only the T cell-dependent mechanism for the development of basophils of both rodents and humans. The most important cytokine for the T cell-dependent mechanism appears to be interleukin-3, whereas for the fibroblast-dependent mechanism it appears to be the ligand for the c-kit receptor (ie, stem cell factor).

Abstract
In surgically excised nasal polyps, most epithelial mast cells were formalin sensitive, chloroacetate esterase (CAE) negative, and chymase negative. Thus, this represents a population of mast cells not identified by staining for CAE. On the other hand, most stromal mast cells were formalin resistant and CAE positive, and although there was some polyp-to-polyp variability in their content of neutral protease, most of these cells were positive for both tryptase and chymase. The percentage of metachromatic cells in the epithelium and the number of metachromatic cells per unit area of polyp tissue did not correlate with an index of allergy skin test reactivity or the serum IgE concentration. The percentage of mast cells surrounded by pericellular tryptase, suggesting activation/degranulation, was significantly higher in the stroma than in the epithelium. The findings demonstrate differences between the stroma and the epithelium in phenotype and state of activation of mast cells; these are postulated to be due to distinct microenvironmental factors that affect mast cells at these sites.

Abstract
Administration of 8-methoxypsoralen followed by ultraviolet A irradiation (PUVA treatment) has been used as a therapy for urticaria pigmentosa. The effect of PUVA treatment on cutaneous mast cells in mice was investigated by using giant granules of mast cells from C57BL/6-bgJ/bgJ (Chediak-Higashi syndrome) mice as a marker. C57BL/6-(+)/+ mice were lethally irradiated and rescued by bone marrow transplantation from C57BL/6-bgJ/bgJ mice. In the radiation chimeras, mast cells in the skin were of +/+ type and mast-cell precursors migrating in the bloodstream were bgJ/bgJ. When PUVA treatment was applied to the skin of the radiation chimeras, the total number of mast cells continued to decrease until the third week after the treatment and then recovered to pre-treatment levels. The initial reduction was attributed to the decrease of +/(+)-type mast cells, and the subsequent recovery to be as a result of the increase of bgJ/bgJ-type mast cells. This observation may explain the fact that the therapeutic effect of PUVA treatment is transient. Symptoms of urticaria pigmentosa become manifest after the cessation of PUVA treatment probably because new mast cells differentiate from bone marrow-derived precursors.

Abstract
Disaggregated embryonic yolk sac cells and circulating peripheral blood cells were obtained from normal murine day 9 embryos, prior to the formation of the fetal liver. These cells were microinjected transplacentally into days 11-15 W mutant anemic fetuses, when the fetal liver was the major hemopoietic organ. In a small proportion of the recipient animals examined after birth, long-term repopulation by the embryonic donor hemopoietic cells was observed. The donor hemopoietic stem cells proliferated and differentiated in the hosts as evidenced by the presence of donor hemoglobins in the growing recipient host animals. Some mothers of the pups were also repopulated by the donor stem cells. These results provide direct evidence that, during early murine embryogenesis, there are functional hemopoietic stem cells which are capable of colonizing the adult hemopoietic organs and probably the fetal liver and spleen to initiate hemopoiesis in these tissues.

Abstract
In spite of the apparent depletion of mast cells in tissues of mutant mice of W/Wv genotype, cells with many features of mast cells do develop when bone marrow cells of W/Wv mice are cultured in the presence of pokeweed mitogen-stimulated spleen cell-conditioned medium (PWM-SCM). In order to resolve this discrepancy and facilitate the analysis of the W mutation, we attempted to establish an in vitro system in which the in vivo defect of W/Wv mice can be reproduced. Cultured mast cells (CMC) were developed from bone marrow cells of either W/Wv or congenic +/+ mice, and then co-cultured with NIH/3T3 mouse fibroblasts in media supplemented only with fetal calf serum (i.e., in the absence of PWM-SCM). Under this condition, CMC from +/+ mice continued to divide and were maintained for more than 4 weeks. The supportive effect of NIH/3T3 cells required close-range interactions with CMC and was not due to synthesis of the known mast cell growth factors, interleukins 3 and 4. By contrast, CMC from W/Wv mice were not maintained, and the number of mast cells remaining after 4 weeks of co-culture was only 1% of the normal +/+ counterparts. Thus, the humoral factor-independent and cell contact-dependent system presented here revealed the intrinsic defects in growth and differentiation of CMC derived from W/Wv mice and might be useful for biochemical and molecular analysis of the gene product(s) encoded at the W locus.

Abstract
Information about the differentiation of mast cells has increased remarkably in the past ten years. This progress has resulted from the introduction of techniques which developed in other fields of experimental hematology. Once mast cells were recognized as a progeny of multipotential hematopoietic stem cells, their unique differentiation processes were clarified. Although most of the progeny of stem cells leave the hematopoietic tissue after maturation, undifferentiated precursors of mast cells leave the hematopoietic tissue. Morphologically, unidentifiable precursors migrate in the bloodstream, invade the connective tissues or the mucosa of the alimentary canal, proliferate, and differentiate into mast cells. Even after their morphological differentiation, some mast cells retain an extensive proliferative potential. There are at least two subpopulations of mast cells: a connective-tissue type and a mucosal type. Connective tissue-type and mucosal mast cells can be distinguished by histochemical, electron microscopical, biochemical and immunological criteria; however, these two types can interchange, and their phenotypes are determined by the anatomical microenvironment in which their final differentiation occurs. Although biochemical natures of the anatomical microenvironment are unknown, molecules that support proliferation and differentiation of mast cells in vitro have been characterized, i.e., interleukin 3 and interleukin 4. In the next ten years, increased information about the differentiation processes will probably induce further understanding of mast cell functions.

Abstract
SUMMARYAggregation chimaeras were constructed by fusing embryos homozygous for sash (Wsh) with fuzzy, leaden beige (fz,ln,bg) homozygotes to investigate the site of action of the beige and leaden loci. The genotype of the hair follicle was identified by fuzzy alleles (+ +fzorfzfz). All melanocytes were derived from the fuzzy leaden beige population, as sash homozygotes do not produce functional melanocytes. Reciprocal recombinant epidermal/ /dermal skin grafts were constructed from 14-day embryonic skin of homozygousfzlnbg and either albino (aa cc) or pink-eyed dilution (pp) embryos to test for any dermal expression of leaden or beige, since the epidermal and dermal genotype of the chimaeric hair follicles could differ.Patches of fuzzy and non-fuzzy hairs were distributed throughout the coats of two of the three chimaeras obtained. The pigmented regions were blue grey, typical of the leaden beige interactive phenotype. Large abnormal beige granules were found in fuzzy and non-fuzzy hairs. Melanocytes in both classes of growing follicles were nucleopetal, typical of leaden. Similarly, the results of the 14-day skin grafts showed that the beige and leaden loci are melanocyte-autonomous.The chimaeras showed a pigment distribution resembling the heterozygous sash phenotype. Thus the 1:1 gene dosage of sash: wild type in heterozygotes and chimaeras has an overall effect on pigment pattern that overrides the predicted random distribution of the melanocyte precursors.

Abstract
Mice of genotype W/Wv have less than 1% of normal mast cells in the skin, stomach, and cecum. In order to further clarify the mechanism of this deficiency, we studied committed mast cell progenitors and multipotent progenitors, which are capable of mast cell differentiation in clonal culture. The relative concentration of mast cell progenitors in the bone marrow, spleen, and peripheral blood of W/Wv mice was similar to that of +/+ mice. However, the cellularity of the marrows of W/Wv mice was 54% of that of their normal littermates. Identification of mast cells was established by metachromatic staining with toluidine blue, transmission electron microscopy, and demonstration of membrane receptors for immunoglobulin E. The time course of colony formation and the morphology of W/Wv mast cell colonies in culture was identical to that of normal littermates. The percentages of mast cells in individual multi-lineage colonies were extremely variable. The histamine content of mast cells derived from W/Wv mice was similar to that of mast cells from +/+ mice. These studies demonstrated the normal capacity for differentiation and proliferation in culture of mast cell progenitors from W/Wv mice.
