Abstract
Chimeric antigen receptor (CAR)-modified T cell therapy has achieved remarkable efficacy in treating hematological malignancies, but it confronts many challenges in treating solid tumors, such as the immunosuppressive microenvironment of the solid tumors. These factors reduce the antitumor activity of CAR-T cells in clinical trials. Therefore, we used the immunocytokine interleukin-12 (IL-12) to enhance the efficacy of CAR-T cell therapy. In this study, we engineered CAR-IL12R54 T cells that targeted mesothelin (MSLN) and secreted a single-chain IL-12 fused to a scFv fragment R54 that recognized a different epitope on mesothelin. The evaluation of the anti-tumor activity of the CAR-IL12R54 T cells alone or in combination with anti-PD-1 antibody in vitro and in vivo was followed by the exploration of the functional mechanism by which the immunocytokine IL-12 enhanced the antitumor activity. CAR-IL12R54 T cells had potency to lyse mesothelin positive tumor cells in vitro. In vivo studies demonstrated that CAR-IL12R54 T cells were effective in controlling the growth of established tumors in a xenograft mouse model with fewer side effects than CAR-T cells that secreted naked IL-12. Furthermore, combination of PD-1 blockade antibody with CAR-IL12R54 T cells elicited durable anti-tumor responses. Mechanistic studies showed that IL12R54 enhanced Interferon-γ (IFN-γ) production and dampened the activity of regulatory T cells (Tregs). IL12R54 also upregulated CXCR6 expression in the T cells through the NF-κB pathway, which facilitated T cell infiltration and persistence in the tumor tissues. In summary, the studies provide a good therapeutic option for the clinical treatment of solid tumors.

Abstract
Mendelian Susceptibility to Mycobacterial Diseases (MSMD) is a primary immunodeficiency disease (PID) characterized by variable susceptibility to weakly virulent mycobacteria (Bacille Calmette-Guerin, BCG) and various intramacrophagic bacteria, fungi, parasites. Mycobacterial disease generally begins in childhood, more rarely during adolescence and adulthood. The pathogenesis of MSMD is the inherited impaired production of interferon gamma (IFN-γ) or inadequate response to it. Autosomal recessive IL12RB1 deficiency is the most common genetic etiology of MSMD. Here we identified three novel compound heterozygous mutations in IL12RB1 gene (c.635G>A, c.765delG; c.632G>C, c.847C>T; c.64G>A, c.1673insGAGCTTCCTGAG) in three Chinese families with MSMD.

Abstract
Interleukin-12 receptor β2 (IL-12Rβ2) is a signaling subunit of heterodimeric receptors for IL-12 and IL-35. It plays important regulatory functions in the development of Th1 cells and in the expression of inflammatory cytokines in mammals and other higher vertebrates. However, little is known about IL-12Rβ2 in teleost fish. In this work, we have cloned and characterized IL-12Rβ2 from grass carp (Ctenopharyngodon idella). The full-length cDNA of grass carp IL-12Rβ2 is 2875 bp, which encodes a mature protein with 741 amino acids. This mature protein contains three fibronectin type III domains, a transmembrane helix, and CXW and WSXWS-like motifs that are characteristic of the type I cytokine receptor family. Phylogenetic analysis revealed that cyprinid fish IL-12Rβ2 formed a single branch, clearly separated from those of other vertebrates. We expressed and purified a recombinant grass carp IL-12Rβ2 protein containing major antigenic regions, which was used to raise a polyclonal antibody. The specificity of the antibody was assessed by Western blotting analysis of whole cell lysates from Escherichia coli cells expressing the recombinant IL-12Rβ2, grass carp intestinal intraepithelial lymphocytes, and cultured C. idella kidney cells. To explore the potential regulatory role of IL-12Rβ2 in inflammation, we generated an intestinal inflammation model by anal intubation of fish with Aeromonas hydrophila. Immunohistochemical staining of the inflamed intestines revealed that IL-12Rβ2 expression is consistent with inflammatory cell recruitment during intestinal inflammation. Real-time quantitative PCR revealed that IL-12Rβ2 is widely expressed in normal tissues and is up-regulated in most tissues after infecting with A. hydrophila. We found that IL-12Rβ2, IL-12p35, and interferon-γ were expressed in similar patterns in the intestines during inflammation. Taken together, our results suggest that IL-12Rβ2 is involved in the regulation of intestinal inflammation.

Abstract
INTRODUCTION Seldom cutaneous leishmaniasis (CL) may present as a lasting and active lesion(s), known as a non-healing form of CL (NHCL). Non-functional type 1 T helper (Th1) cells are assumed the most important factor in the outcome of the disease. The present study aims to assess some molecular defects that potentially contribute to Th1 impairment in NHCL. METHODS AND ANALYSIS This prospective observational study will be implemented among five groups. The first and second groups comprise patients afflicted with non-healing and healing forms of CL, respectively. The third group consists of those recovered participants who have scars as a result of CL. Those participants who have never lived or travelled to endemic areas of leishmaniasis will comprise the fourth group. The fifth group comprises participants living in hyperendemic areas for leishmaniasis, although none of them have been afflicted by CL. The aim is to recruit 10 NHCL cases and 30 participants in each of the other groups. A leishmanin skin test (LST) will be performed to assess in vivo immunity against the Leishmania infection. The cytokine profile (interleukin (IL)-12p70, interferon (IFN)-γ, C-X-C motif chemokine ligand (CXCL)-11 and IL-17a) of the isolated peripheral blood mononuclear cells (PBMCs) will be evaluated through ELISA. Real-time PCR will determine the C-X-C motif chemokine receptor (CXCR)-3 and IL-17a gene expression and expression of IL-12Rβ1 will be assessed by flow cytometry. Furthermore, IL-12B and IL-12RB1 mutation analysis will be performed. DISCUSSION It is anticipated that the outcome of the current study will identify IL-12B and IL-12RB1 mutations, which lead to persistent lesions of CL. Furthermore, our expected results will reveal an association between NHCL and pro-inflammatory cytokines (IL-12p70, IFN-γ IL-17a and CXCL-11), as well as CXCR-3 expression. ETHICS AND DISSEMINATION This study has been approved by a local ethical committee. The final results will be disseminated through peer-reviewed journals and scientific conferences.

Abstract
Cytokines secreted from dendritic cells (DCs) play an important role in the regulation of T helper (Th) cell differentiation and activation into effector cells. Therefore, controlling cytokine secretion from DCs may potentially regulate Th differentiation/activation. DCs also induce de-novo generation of regulatory T cells (Treg) that modulate the immune response. In the current study we used the mixed leukocyte reaction (MLR) to investigate the effect of allospecific Treg on IL-12, TNFα and IL-6 secretion by DCs. Treg cells were found to markedly down-regulate IL-12 secretion from DCs following stimulation with TLR7/8 agonist. This down-regulation of IL-12 was neither due to a direct suppression of its production by the DCs nor a result of marked DC death. We found that IL-12 was rather actively consumed by Treg cells. IL-12 consumption was mediated by a subpopulation of IL-12Rβ2-expressing Treg cells and was dependent on MHC class-II expressed on dendritic cells. Furthermore, IL-12 consumption by Tregs increased their suppressive effect on T cell proliferation and Th1 activation. These results provide a new pathway of Th1 response regulation where IL-12 secreted by DCs is consumed by a sub-population of IL-12Rβ2-expressing Treg cells. Consumption of IL-12 by Tregs not only reduces the availability of IL-12 to Th effector cells but also enhances the Treg immunosuppressive effect. This DC-induced IL-12Rβ2-expressing Treg subpopulation may have a therapeutic advantage in suppressing Th1 mediated autoimmunity.

Abstract
Ly6C+ inflammatory monocytes are essential to host defense against Toxoplasma gondii, Listeria monocytogenes and other infections. During T. gondii infection impaired inflammatory monocyte emigration results in severe inflammation and failure to control parasite replication. However, the T. gondii factors that elicit these monocytes are unknown. Early studies from the Remington laboratory showed that mice with a chronic T. gondii infection survive lethal co-infections with unrelated pathogens, including L. monocytogenes, but a mechanistic analysis was not performed. Here we report that this enhanced survival against L. monocytogenes is due to early reduction of bacterial burdens and elicitation of Ly6C+ inflammatory monocytes. We demonstrate that a single TLR11/TLR12 ligand profilin (TgPRF) was sufficient to reduce bacterial burdens similar to T. gondii chronic infection. Stimulation with TgPRF was also sufficient to enhance animal survival when administered either pre- or post-Listeria infection. The ability of TgPRF to reduce L. monocytogenes burdens was dependent on TLR11 and required IFN-γ but was not dependent on IL-12 signaling. TgPRF induced rapid production of MCP-1 and resulted in trafficking of Ly6Chi CCR2+ inflammatory monocytes and Ly6G+ neutrophils into the blood and spleen. Stimulation with TgPRF reduced L. monocytogenes burdens in mice depleted with the Ly6G specific MAb 1A8, but not in Ly6C/Ly6G specific RB6-8C5 depleted or CCR2−/− mice, indicating that only inflammatory monocytes are required for TgPRF-induced reduction in bacterial burdens. These results demonstrate that stimulation of TLR11 by TgPRF is a mechanism to promote the emigration of Ly6Chi CCR2+ monocytes, and that TgPRF recruited inflammatory monocytes can provide an immunological benefit against an unrelated pathogen. Toxoplasma gondii is an apicomplexan parasite that can infect all warm blooded animals, but rodent species are considered the primary reservoirs. Mice that are infected with T. gondii become more resistant to lethal infection with other pathogens. Ly6C+ inflammatory monocytes are innate immune cells that are critical for defense against T. gondii and other infections. Mice with defects in the ability to recruit inflammatory monocytes fail to control T. gondii replication and succumb to overwhelming inflammation. In this study we used a co-infection model to explain why T. gondii-infected mice are more resistant to the bacterium Listeria monocytogenes. We show that stimulation of the rodent specific Toll-like receptor TLR11 by the T. gondii ligand profilin can recruit inflammatory monocytes, and that these monocytes can protect the host against L. monocytogenes. These findings make profilin an important tool for the study of monocyte biology during T. gondii infection of rodents and are especially interesting given that TLR11 is nonfunctional in humans and other vertebrates.

Abstract
IL-12 and IL-23 cytokines respectively drive Th1 and Th17 type responses. Yet, little is known regarding the biology of these receptors. As the IL-12 and IL-23 receptors share a common subunit, it has been assumed that these receptors are co-expressed. Surprisingly, we find that the expression of each of these receptors is restricted to specific cell types, in both mouse and human. Indeed, although IL-12Rβ2 is expressed by NK cells and a subset of γδ T cells, the expression of IL-23R is restricted to specific T cell subsets, a small number of B cells and innate lymphoid cells. By exploiting an IL-12- and IL-23-dependent mouse model of innate inflammation, we demonstrate an intricate interplay between IL-12Rβ2 NK cells and IL-23R innate lymphoid cells with respectively dominant roles in the regulation of systemic versus local inflammatory responses. Together, these findings support an unforeseen lineage-specific dichotomy in the in vivo role of both the IL-12 and IL-23 pathways in pathological inflammatory states, which may allow more accurate dissection of the roles of these receptors in chronic inflammatory diseases in humans.

Abstract
Our objective was to replicate previously reported associations between cytokine and cytokine receptor SNPs and humoral and CMI (cell-mediated immune) responses to measles vaccine. All subjects (n=758) received two doses of MMR (measles/mumps/rubella) vaccine. From these subjects, candidate cytokine and cytokine receptor SNPs were genotyped and analyzed in 29-30 subjects falling into one of four "extreme" humoral (Ab(high/low)) and CMI (CMI(high/low)) response quadrants. Associations between seven SNPs (out of 11 in the discovery study) and measles-specific neutralizing antibody levels and IFN-γ ELISPOT responses were evaluated using chi-square tests. We found one replicated association for SNP rs372889 in the IL12RB1 gene (P=0.03 for Ab(high)CMI(high) vs. Ab(low)CMI(low)). Our findings demonstrate the importance of replicating genotypic-phenotypic associations, which can be achieved using immunophenotypic extremes and smaller sample sizes. We speculate that IL12RB1 polymorphisms may affect IL-12 and IL-23 binding and downstream effects, which are critical cytokines in the CMI response to measles vaccine.

Abstract
Interleukin 35 (IL-35) belongs to the IL-12 family of heterodimeric cytokines but has a distinct functional profile. IL-35 suppresses T cell proliferation and converts naive T cells into IL-35-producing induced regulatory T cells (iTr35 cells). Here we found that IL-35 signaled through a unique heterodimer of receptor chains IL-12Rβ2 and gp130 or homodimers of each chain. Conventional T cells were sensitive to IL-35-mediated suppression in the absence of one receptor chain but not both receptor chains, whereas signaling through both chains was required for IL-35 expression and conversion into iTr35 cells. Signaling through the IL-35 receptor required the transcription factors STAT1 and STAT4, which formed a unique heterodimer that bound to distinct sites in the promoters of the genes encoding the IL-12 subunits p35 and Ebi3. This unconventional mode of signaling, distinct from that of other members of the IL-12 family, may broaden the spectrum and specificity of IL-35-mediated suppression.

Abstract
Acute myeloid leukemia is a haematopoietic malignancy originating from the transformation of myeloid progenitors that proliferate and accumulate in the bone marrow. In AML patients the survival rate at 5 years is 40-50% highlighting the need for novel therapies. In this study we have asked whether IL-12, an immuno-modulatory cytokine with anti-tumor activity, may inhibit directly AML cell growth. We show that the human AML cell lines U937, K562 and THP-1 expressed both chains of the IL-12 receptor (R), i.e. IL-12Rβ1 and IL-12Rβ2. IL-12 inhibited the angiogenic potential of AML cells in vitro, but did not affect their survival or proliferation. In vivo experiments were performed using SCID-NOD mice injected intraperitoneally (i.p.) with the human U937 AML cell line and subsequently treated with human recombinant IL-12 or PBS i.p. Histological, immunohistochemical and flow cytometric analyses on explanted tumors revealed that IL-12 reduced new vessel formation, induced apoptosis and inhibited tumor cell proliferation. Studies on a panel of angiogenesis related genes in explanted tumors using PCR arrays showed significantly down-regulated expression of numerous pro-angiogenic genes including VEGF-C, IL-6, IL-8, CXCL1, CXCL6 and alanyl aminopeptidase in IL-12 vs PBS treated mice. This study shows for the first time that IL-12 targets directly AML cell growth and paves the way to further investigation of IL-12 as potential drug for AML treatment.

Abstract
Genetic defects of interleukin (IL)-12/23-and interferon (IFN)-gamma-mediated immunity can cause increased susceptibility to intracellular microbes. Among these defects, a mutation of the gene encoding the IL-12 receptor beta1 (IL-12Rbeta1) is the most common worldwide. A 12-year old Thai boy with pre-existing neurofibromatosis type 1 (NF1) was evaluated for primary immunodeficiency after a history of tuberculous lymphadenitis, recurrent Salmonella infections and nocardiosis. Flow cytometry of phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMCs) revealed a defect in the IL-12Rbeta1 surface expression. A genetic study showed a novel nonsense homozygous mutation of the IL12RB1 gene in exon 4 (402C > A), confirming the diagnosis of IL-12Rbeta1 deficiency. This is the first case report of a primary IL-12Rbeta1 deficiency in Thailand with the interesting finding of a coexisting NF1.

Abstract
IL-16, a leukocyte chemoattractant factor (LCF), is involved in the disease process of multiple sclerosis and other autoimmune disorders. However, mechanisms by which this LCF is expressed are poorly understood. The present study underlines the importance of IL-12 p40 homodimer (p40(2)), the so-called biologically inactive molecule, in inducing the expression of IL-16 in primary mouse and human microglia, mouse BV-2 microglial cells, mouse peritoneal macrophages, and RAW264.7 cells. In contrast, IL-12 p70, the bioactive heterodimeric cytokine, was unable to induce the expression of IL-16 in any of these cell types. Similarly IL-12 p40(2) also induced the activation of IL-16 promoter in microglia. Among various stimuli tested, p40(2) was the most potent one followed by p40 monomer, IL-16 and IL-23 in inducing the activation of IL-16 promoter in microglial cells. Furthermore, induction of IL-16 mRNA expression by over-expression of p40, but not p35, cDNA and induction of IL-16 expression by p40(2) in microglia isolated from IL-12p35 (-/-) mice confirm that p40, but not p35, is responsible for the induction of IL-16. Finally, by using primary microglia isolated from IL-12Rbeta1 (-/-) and IL-12Rbeta2 (-/-) mice, we demonstrate that p40(2) induces the expression of this LCF via IL-12Rbeta1 but not IL-12Rbeta2. These results delineate a novel biological function of p40(2) and raise the possibility that biological function of IL-12 p40(2) may be different from IL-12 p70.

Abstract
Interleukin-12 (IL-12) is a key cytokine for the development of T helper type 1 (Th1) responses; however, naïve CD4(+) T cells do not express IL-12Rbeta2, and are therefore unresponsive to IL-12. We have examined the mechanisms that control Th1-specific expression of the human IL-12Rbeta2 gene at early time points after T-cell stimulation. We have identified a Th1-specific enhancer element that binds signal transducer and activator of transcription 4 (STAT4) in vivo in developing Th1 but not Th2 cells. T-cell receptor (TCR) signaling induced histone hyperacetylation and recruitment of BRG1, the ATPase subunit of the SWI/SNF-like BAF chromatin remodeling complex, to the IL-12Rbeta2 regulatory regions and was associated with low-level gene transcription at the IL-12Rbeta2 locus. However, high-level IL-12Rbeta2 expression required TCR triggering in the presence of IL-12. Our results indicate a synergistic role of TCR-induced chromatin remodeling and cytokine-induced STAT4 activation to direct IL-12Rbeta2 expression during Th1 cell development.

Abstract
IL-12p40 is known as a component of the bioactive cytokines interleukin (IL)-12 and IL-23 but it is not widely recognized as having intrinsic functional activity. Recent publications have altered this perception and support an independent role for IL-12p40. IL-12p40 is induced in excess over the other subunits of IL-12 and IL-23 and can exist in a monomeric or homodimeric form. Its most widely appreciated function is to provide a negative feedback loop by competitively binding to the IL-12 receptor. However, IL-12p40 acts as a chemoattractant for macrophages and promotes the migration of bacterially stimulated dendritic cells. It is associated with several pathogenic inflammatory responses such as silicosis, graft rejection and asthma but it is also protective in a mycobacterial model. An appreciation of the independent function of IL-12p40 is important for improving our understanding of both protective and pathogenic immune responses.
