Abstract
BACKGROUND AND AIM The artificial sweetener acesulfame potassium (ACK) is officially approved as safe for intake and has been used in processed foods. However, ACKs have been reported to induce metabolic syndrome, along with alteration of the gut microbiota in mice. In recent years, studies have suggested that this artificial sweetener promotes myeloperoxidase reactivity in Crohn's disease-like ileitis. We aimed to investigate the effect of ACK on the intestinal mucosa and gut microbiota of normal mice. METHODS Acesulfame potassium was administered to C57BL/6J mice (8 weeks old) via free drinking. Intestinal damage was evaluated histologically, and messenger RNA (mRNA) levels of TNF-α, IFN-γ, IL1-β, MAdCAM-1, GLP1R, and GLP2R were determined with quantitative reverse transcription polymerase chain reaction (qRT-PCR). Immunohistochemistry was performed to examine the expression of MAdCAM-1 in the small intestine. The composition of gut microbiota was assessed using high-throughput sequencing. We performed intravital microscopic observation to examine if ACK altered lymphocyte migration to the intestinal microvessels. RESULTS Acesulfame potassium increased the expression of proinflammatory cytokines, decreased the expression of GLP-1R and GLP-2R, and induced small intestinal injury with an increase in intestinal permeability, and ACK treatment induced microbial changes, but the transfer of feces alone from ACK mice did not reproduce intestinal damage in recipient mice. ACK treatment significantly increased the migration of lymphocytes to intestinal microvessels. CONCLUSION Acesulfame potassium induces dysbiosis and intestinal injury with enhanced lymphocyte migration to intestinal mucosa. Massive use of non-caloric artificial sweeteners may not be as safe as we think.

Abstract
The enhanced recruitment of leukocytes to the inflamed colon is a key feature of ulcerative colitis (UC). The gut-specific adhesion molecules involved in leukocyte recruitment have emerged as recent therapeutic targets. Nicotine absorbed from smoking has been reported to work protectively in UC patients. Our hypothesis is that nicotine may suppress the aberrant leukocyte recruitment and colonic inflammation via the suppression of the overexpressed gut-specific adhesion molecules in the inflamed colon. To test this hypothesis, the severity of colitis and the degree of leukocyte recruitment induced by gut-specific adhesion molecules were assessed in dextran sulfate sodium (DSS) colitis mice (C57BL/6J mice treated with 3% DSS) with or without nicotine treatment. We also studied the in vitro changes in the expression of adhesion molecules by using a vascular endothelial cell line. DSS-induced colitis was accompanied by increases in disease activity index (DAI), histological score, recruitment of leukocytes, and the expression of adhesion molecules, mucosal vascular addressin cell adhesion molecule-1 (MAdCAM-1) and VCAM-1. Nicotine treatment significantly attenuated MAdCAM-1 expression, leukocyte recruitment, DAI, and histological score. The expression of β7-integrin, the ligand for MAdCAM-1, on leukocytes was not affected by nicotine treatment. In vitro study, the TNF-α-enhanced mRNA expression of MAdCAM-1 was reduced by the coadministration of nicotine in a dose-dependent manner, possibly via nicotinic receptor activation. These results supported our hypothesis that nicotine treatment ameliorated colitis through the suppression of MAdCAM-1 expression on the microvessels in the inflamed colon. Further investigation is warranted on the role of nicotine in the treatment of UC.

Abstract
Naive lymphocytes systemically recirculate for immunosurveillance inspecting foreign antigens and pathogens in the body. Trafficking behavior such as the migration pathway and transit time within the gastrointestinal tract, however, remains to be elucidated. Rat thoracic duct lymphocytes (TDLs) were transferred to a congeneic host that had undergone mesenteric lymphadenectomy. The migration pathway was investigated using newly developed four-color immunohistochemistry and immunofluorescence. Donor TDLs showed rapid transition in gut tissues from which they emerged in mesenteric lymph around 4 h after intravenous injection. Immunohistochemistry showed that donor TDLs predominantly transmigrated across high endothelial venules (HEVs) at the interfollicular area of the Peyer's patches (PPs), then exited into the LYVE-1+ efferent lymphatics, that were close to the venules. The rapid recirculation depended largely on the local expression of unsulfated sialyl-Lewis X on these venules where putative dendritic cells (DCs) were associated underneath. Recruited naive T cells briefly made contact with resident DCs before exiting to the lymphatics in the steady state. In some transplant settings, however, the T cells retained contact with DCs and were sensitized and differentiated into activated T cells. In conclusion, we directly demonstrated that lymphocyte recirculation within the gut is a very rapid process. The interfollicular area of PPs functions as a strategically central site for rapid immunosurveillance where HEVs, efferent lymphatics and resident DCs converge. PPs can, however, generate alloreactive T cells, leading to exacerbation of graft-versus-host disease or gut allograft rejection.

Abstract
Chemokine receptor CXCR4 promotes B cell localization to CXCL12+ perilymphatic zones and egress from Peyer’s patches. Peyer’s patches (PPs) play a central role in supporting B cell responses against intestinal antigens, yet the factors controlling B cell passage through these mucosal lymphoid tissues are incompletely understood. We report that, in mixed chimeras, CXCR4-deficient B cells accumulate in PPs compared with their representation in other lymphoid tissues. CXCR4-deficient B cells egress from PPs more slowly than wild-type cells, whereas CXCR5-deficient cells egress more rapidly. The CXCR4 ligand, CXCL12, is expressed by cells adjacent to lymphatic endothelial cells in a zone that abuts but minimally overlaps with the CXCL13+ follicle. CXCR4-deficient B cells show reduced localization to these CXCL12+ perilymphatic zones, whereas CXCR5-deficient B cells preferentially localize in these regions. By photoconverting KikGR-expressing cells within surgically exposed PPs, we provide evidence that naive B cells transit PPs with an approximate residency half-life of 10 h. When CXCR4 is lacking, KikGR+ B cells show a delay in PP egress. In summary, we identify a CXCL12hi perilymphatic zone in PPs that plays a role in overcoming CXCL13-mediated retention to promote B cell egress from these gut-associated lymphoid tissues.

Abstract
Lysophosphatidic acid (LPA) has a critical role in lymphocyte migration to secondary lymphoid organs. Autotaxin (ATX)/lysophospholipase D, in the vascular endothelium, is the main enzyme involved in LPA production. Whether ATX is involved in pathological lymphocyte migration to the inflamed mucosa has not been studied. We investigated the involvement of ATX in inflammatory bowel disease patients and two murine models of colitis. Tissue samples were obtained by intestinal biopsies from patients with Crohn's disease and those with ulcerative colitis with informed consent. ATX immunoreactivity was colocalized with MAdCAM-1-positive high-endothelial-like vessels, close to sites of lymphocyte infiltration. Enhanced expression of ATX mRNA was observed in the inflamed mucosa from Crohn's disease and ulcerative colitis patients. ATX mRNA expression level was remarkably higher in the actively inflamed mucosa than in the quiescent mucosa in the same patient. In the T-cell-transferred mouse model, ATX mRNA expression level gradually increased as colitis developed. In the dextran sodium sulfate mouse model, the expression level was considerably higher in colonic mucosa of chronically developed colitis than in colonic mucosa of acute colitis. Administration of an ATX inhibitor, bithionol, remarkably decreased lymphocyte migration to the intestine and ameliorated both dextran sodium sulfate-induced colitis and CD4-induced ileocolitis. In transwell assays, administration of bithionol or 1-bromo-3(s)-hydroxy-4-(palmitoyloxy) butylphosphonate (BrP-LPA) significantly decreased transmigration of splenocytes through high-endothelial-like vessels induced by TNF-α. We conclude that enhanced expression of ATX in the active mucosa has been implicated in the pathophysiology of inflammatory bowel disease through enhancing aberrant lymphocyte migration to the inflamed mucosa.

Abstract
Although enhanced lymphocyte trafficking is associated with colitis formation, little information about its regulation is available. The aim of this study was to examine how the murine liver and activation-regulated chemokine (mLARC/CCL20) contributes to lymphocyte recruitment in concert with vascular adhesion molecules in murine chronic experimental colitis. T and B lymphocytes isolated from the spleen were fluorescence-labelled and administered to recipient mice. Lymphocyte adhesion to microvessels of the colonic mucosa and submucosa was observed with an intravital microscope. To induce colitis, the mice received two cycles of treatment with 2% dextran sodium sulphate (DSS). In some of the experiments antibodies against the adhesion molecules or anti-mLARC/CCL20 were administered, or CC chemokine receptor 6 (CCR6) of the lymphocytes was desensitized with excess amounts of mLARC/CCL20. Significant increases in T and B cell adhesion to the microvessels of the DSS-treated mucosa and submucosa were observed. In chronic colitis, the accumulation of lymphocytes was significantly inhibited by anti-mucosal addressin cell adhesion molecule (MAdCAM)-1 mAb, but not by anti-vascular cell adhesion molecule-1. In DSS-treated colonic tissue, the expression of mLARC/CCL20 was significantly increased, the blocking of mLARC/CCL20 by monoclonal antibody or the desensitization of CCR6 with mLARC/CCL20 significantly attenuated the DSS-induced T and B cell accumulation. However, the combination of blocking CCR6 with MAdCAM-1 did not further inhibit these accumulations. These results suggest that in chronic DSS-induced colitis, both MAdCAM-1 and mLARC/CCL20 may play important roles in T and B lymphocyte adhesion in the inflamed colon under flow conditions.

Abstract
Scenescence-induced changes in gut-associated lymphoid tissues may contribute largely to the impaired immune responses during aging. Age-related changes in lymphocyte recirculations were investigated in Peyer's patches of rat small intestine. Cell dynamics of labeled T lymphocytes were observed under an intravital fluorescence microscope and compared between young and aged rats. Lymphocyte transport through intestinal lymph was decreased in aged rats. The lymphocyte rolling and adherence in postcapillary venules (PCV) of Peyer's patches was also significantly impaired in aged rats, with decreased expression of L-selectin on lymphocyte surfaces. Immunohistochemical analysis revealed a significant decrease in the CD8-positive cell population in Peyer's patches of the aged group, although mucosal addressin cell adhesion molecule-1 (MAdCAM-1) expression in postcapillary venules was unaltered. Lymphocyte adoptive-transfer studies indicated that although both the donor and recipient factors influence the adherence of T cells, the former may play a predominant role in the age-related change. This study clearly demonstrated in situ that T cell migration into Peyer's patches is significantly decreased in the aged intestine, which may reflect the impaired immune responses in the aging process.

Abstract
Few models have described a chronic food allergy with morphological changes in the intestinal mucosa. Here we established an ovalbumin (OVA)-induced, cell-mediated, allergic rat model and examined lymphocyte migration in the gut. Brown Norway rats were intraperitoneally sensitized to OVA and then given 10 mg OVA/day by gastric intubation for 6 wk. Lymphocyte subsets and adhesion molecules were examined immunohistochemically, and the migration of T lymphocytes to microvessels of Peyer's patches and villus mucosa was observed by using an intravital microscope. Serum OVA-specific IgG and IgE levels were increased in animals repeatedly exposed to OVA. Significant villus atrophy and increased crypt depth was accompanied by increased infiltration of T lymphocytes in the small intestinal mucosa of the group given OVA. Expression of rat mast cell protease II and of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) was also increased in these groups. The administration of anti-MAdCAM-1 antibody significantly attenuated the OVA-induced changes in the mucosal architecture and in CD4 T lymphocyte infiltration. Intravital observation demonstrated that in rats with a chronic allergy, T lymphocytes significantly accumulated in villus microvessels as well as in Peyer's patches via a MAdCAM-1-dependent process. Our model of chronic food allergy revealed that lymphocyte migration was increased with MAdCAM-1 upregulation.

Abstract
Dendritic cells (DCs) are continuously transported from the intestine to mesenteric lymph nodes (MLNs). The objective of this study was to determine the migration kinetics of DCs via intestinal lymph and to investigate regulatory factors affecting their migration in vivo. DCs were obtained from spleen or thoracic duct lymph of mesenteric lymphadenectomized rats. The DCs were fluorescently labeled and injected into the subserosa of the small intestine near the cecum, and their migration patterns into MLNs were determined. Isolated DCs from intestinal lymph express intercellular adhesion molecule-1 (ICAM-1), CD11b/c, CD80/86, and major histocompatibility complex class II but maintain their ability to phagocytize latex particles, suggesting the presence of immature DCs. The isolated DCs accumulated in MLNs in a time-dependent manner with maximal accumulation at 48 h. Cytokine-induced maturation of lymph DCs did not cause a change in cell number but accelerated their transport into MLNs with a maximum at 24 h. Splenic DCs showed an intermediate level of maturation and a migration pattern similar to mature DCs. Inhibition of ICAM-1 or CD11b/c did not affect DC migration. Migration of mature DCs to MLNs was specifically blocked by desensitization of CCR7 with CCL21. In contrast, freshly isolated lymph DCs were not chemotactic for CCL21, but their migration to MLNs was mainly inhibited by desensitization of CCR6 with CCL20. The migratory ability of DCs correlates well with their degree of maturation, and different chemokine/chemokine receptor use may be the main regulator of DC migration kinetics through intestinal lymph.

Abstract
While CCR7 ligands direct T cell trafficking into lymph nodes (LNs) and Peyer's patches (PPs), chemokines that regulate B cell trafficking across high endothelial venules (HEVs) remain to be fully elucidated. Here we report that CXC chemokine ligand (CXCL)13 (B lymphocyte chemoattractant) is detected immunohistologically in the majority of HEVs in LNs and PPs of nonimmunized mice. Systemically administered anti-CXCL13 Ab bound to the surface of approximately 50% of HEVs in LNs and PPs, but not to other types of blood vessels, indicating that CXCL13 is expressed in the HEV lumen. In CXCL13-null mice, B cells rarely adhered to PP HEVs, whereas T cells did efficiently. Superfusion of CXCL13-null PPs with CXCL13 restored the luminal presentation of CXCL13 and also B cell arrest in PP HEVs at least partially. Collectively, these results indicate that CXCL13 expressed in the HEV lumen plays a crucial role in B cell trafficking into secondary lymphoid tissues such as PPs.

Abstract
The interaction of activated leukocytes with the rheumatoid synovial environment is a key process in arthritis. Understanding this process will play an important role in designing effective treatments. In vivo imaging approaches combined with molecular genetics in animal models provide important tools to address these issues. The present review will focus on approaches to in vivo imaging, with particular attention to approaches that are proving useful for, or have promise for, research on animal models of rheumatoid arthritis. These approaches will probably shed light on the specific local mechanisms involved in chronic inflammation and provide real time monitoring approaches to follow cellular and molecular events related to disease development.

Abstract
Relatively little is known about how recirculation of lymphocytes through the inflamed intestinal mucosa is regulated. The aim of this study was to investigate the dynamic process of T lymphocyte-endothelial cell adhesion in TNF-alpha-challenged murine colonic mucosa by intravital microscopy. T lymphocytes from spleen (SPL) and intestinal lamina propria (LPL) were fluorescence labeled, and their adhesion to microvessels in the colonic mucosa was observed. In TNF-alpha (25 microg/kg)-stimulated colonic venules, an enhanced adhesion of SPL and LPL was demonstrated, with dominant recruitment of LPLs. The magnitude of the increased LPL adhesion was more significant in the colon than in the small intestine. These T lymphocyte interactions in the colonic mucosa were significantly reduced by blocking MAbs against either mucosal addressin cell adhesion molecule-1 (MAdCAM-1), VCAM-1, alpha(4)-integrin, or beta(7)-integrin but not by anti-ICAM-1. Immunohistochemistry revealed significant MAdCAM-1 expression in the lamina propria and VCAM-1 expression in the submucosa of TNF-alpha-treated colon. Spatial heterogeneity of MAdCAM-1 and VCAM-1 activation following TNF-alpha challenge may promote specific T lymphocyte recruitment in the inflamed colonic mucosa.

Abstract
B cell entry to lymph nodes and Peyer's patches depends on chemokine receptor signaling, but the principal chemokine involved has not been defined. Here we show that the homing of CXCR4-/- B cells is suppressed in CCL19 (ELC)- and CCL21 (SLC)-deficient paucity of lymph node T cells mice, but not in wild-type mice. We also find that CXCR4 can contribute to T cell homing. Using intravital microscopy, we find that B cell adhesion to high endothelial venules (HEVs) is disrupted when CCR7 and CXCR4 are predesensitized. In Peyer's patches, B cell entry is dependent on CXCR5 in addition to CCR7/CXCR4. CXCL12 (SDF1) is displayed broadly on HEVs, whereas CXCL13 (BLC) is found selectively on Peyer's patch follicular HEVs. These findings establish the principal chemokine and chemokine receptor requirements for B cell entry to lymph nodes and Peyer's patches.

Abstract
BACKGROUND & AIMS Although the recirculation of lymphocytes through the intestinal mucosa is important for the specific immune defense, the homing of lamina propria lymphocytes (LPLs) has not been clearly understood. The aim of this study is to compare, under an intravital microscope, the dynamic process of lymphocyte-endothelium recognition and binding in the murine intestinal mucosa of T lymphocytes from the lamina propria of intestine to that of T lymphocytes from the spleen. METHODS LPLs isolated from nonlymphoid areas of the small intestine and spleen (SPL) were fluorescence-labeled and injected into a jugular vein of recipient mice. Microvessels of the villus mucosa and ileal Peyer's patches were observed under an intravital fluorescence microscope, and the effects of anti-adhesion-molecule antibodies on lymphocyte-endothelial interaction were investigated. RESULTS LPLs accumulated abundantly in the microvessels of villus tips but not in the submucosal venules or postcapillary venules of Peyer's patches, where SPLs migrated selectively. The accumulation of LPLs in the villus tips was almost completely inhibited by anti-beta7-integrin and was significantly inhibited by anti-mucosal addressin cell-adhesion molecule 1 (MAdCAM-1) and anti-alpha4-integrin. Significant MAdCAM-1 expression was observed in the microvessels of the villus mucosa. Some SPLs adhered to the nonlymphoid mucosa, but most soon detached. CONCLUSIONS It was shown in vivo for the first time that T lymphocytes from the lamina propria but not from the spleen adhere selectively, mostly via alpha4beta7 and MAdCAM-1, to the microvessels of villus tips of the intestine, but not to the postcapillary venules of Peyer's patches.

Abstract
Previous studies have revealed that the expression of several endothelial cell adhesion molecules [e.g., intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and mucosal addressin cell adhesion molecule 1 (MAdCAM-1)] is dramatically elevated in the chronically inflamed colonic vasculature of severe combined immunodeficient (SCID) mice reconstituted with congenic CD4+, CD45RB(high) T lymphocytes. The objective of this study was to define the contribution of different endothelial cell adhesion molecules to the lymphocyte-endothelial cell (L/E) adhesion observed in the colonic microvasculature in this experimental model of inflammatory bowel disease. Fluorescently labeled T lymphocytes, isolated from spleens of normal BALB/C mice, were injected intravenously into SCID mice that had been reconstituted with CD4+, CD45RB(high) T lymphocytes either before (3 wk after reconstitution) or after (7 wk postreconstitution) the onset of clinical signs of colitis (i.e., diarrhea, loss of body wt). Intravital fluorescence microscopy was used to quantify L/E adhesion in different-sized venules of the colonic submucosa during the development of colitis. L/E adhesion was noted in some segments of the vasculature in precolitic SCID mice (3 wk after reconstitution) but not in similar-sized vessels of control (wild type and SCID) mice. L/E adhesion was observed in a greater proportion of venules and occurred with greater intensity in the mucosa of colitic mice (7 wk postreconstitution). Pretreatment with a blocking monoclonal antibody against MAdCAM-1, but not ICAM-1 or VCAM-1, significantly and profoundly reduced L/E adhesion in colitic mice. Immunohistochemical staining also revealed the localization of T cells on colonic endothelial cells expressing MAdCAM-1. These findings indicate that MAdCAM-1 is largely responsible for recruiting T lymphocytes into inflamed colonic tissue.

Abstract
Chemokines play an important role in establishing the distribution of lymphocyte subpopulations in primary and secondary lymphoid tissues and in the recruitment of leukocytes to sites of inflammation. However, the potential of chemokines to down-regulate immune responses has not been demonstrated. We now show that certain chemokine gradients have the potential to suppress T cell activation by preventing formation of the immunological synapse, the specialized cell-cell junction that forms before a T cell can be fully activated. Our data reveals an immunosuppressive potential of chemokines engaging the CXCR3 and CCR7 receptors, but not the CXCR4, CCR2, CCR4, or CCR5 receptors. These results suggest a novel mechanism for T cell ignorance of agonist MHC-peptide complexes based on dominant chemokine gradients.

Abstract
Mucosal addressin cell adhesion molecule-1 (MAdCAM-1) is essential for lymphocyte trafficking to gut-associated lymphoid tissues and is implicated in inflammatory disorders in the gut and pancreatic islets. In this study, we examined the functional role of MAdCAM-1 during rat ontogeny using newly generated specific mAb. As previously observed in mice and humans, MAdCAM-1 was preferentially expressed in high endothelial venules (HEV) in gut-associated lymphoid tissues and venules of lamina propria in adult rats. Lymphocyte rolling and adhesion on HEV in Peyer's patches (PP) were completely abrogated with neutralizing anti-MAdCAM-1 mAb, in agreement with the notion that MAdCAM-1 is the principal HEV ligand for lymphocyte rolling and adhesion in adult PP. In the developing gastrointestinal tract, MAdCAM-1 was widely expressed in the venules of the lamina propria of fetal rats. In addition, MAdCAM-1 was also expressed in follicular dendritic cells in the neonatal PP. Interestingly, MAdCAM-1 expression was found also in nonmucosal tissues during ontogeny. MAdCAM-1 was transiently expressed in blood vascular endothelial cells in the fetal skin and neonatal thymus. Notably, MAdCAM-1-positive blood vessels were localized mainly in the cortico-medullary junction in the neonatal thymus and about 10-20% of thymocytes, most of which were either CD4, CD8 double positive or single positive specifically reacted with soluble MAdCAM-1 via integrin alpha4beta7. After birth, MAdCAM-1 expression in thymus blood vessels disappeared and concomitantly, the soluble MAdCAM-1-reactive thymocytes were rapidly down-regulated. Our results suggest that MAdCAM-1 functions as a vascular addressin in not only mucosal, but also nonmucosal lymphoid tissues during ontogeny.

Abstract
Chemokines have been hypothesized to contribute to the selectivity of lymphocyte trafficking not only as chemoattractants, but also by triggering integrin-dependent sticking (arrest) of circulating lymphocytes at venular sites of extravasation. We show that T cells roll on most Peyer's patch high endothelial venules (PP-HEVs), but preferentially arrest in segments displaying high levels of luminal secondary lymphoid tissue chemokine (SLC) (6Ckine, Exodus-2, thymus-derived chemotactic agent 4 [TCA-4]). This arrest is selectively inhibited by functional deletion (desensitization) of CC chemokine receptor 7 (CCR7), the receptor for SLC and for macrophage inflammatory protein (MIP)-3beta (EBV-induced molecule 1 ligand chemokine [ELC]), and does not occur in mutant DDD/1 mice that are deficient in these CCR7 ligands. In contrast, pertussis toxin-sensitive B cell sticking does not require SLC or MIP-3beta signaling, and occurs efficiently in SLC(low/-) HEV segments in wild-type mice, and in the SLC-negative HEVs of DDD/1 mice. Remarkably, sites of T and B cell firm adhesion are segregated in PPs, with HEVs supporting B cell accumulation concentrated in or near follicles, the target domain of most B cells entering PPs, whereas T cells preferentially accumulate in interfollicular HEVs. Our findings reveal a fundamental difference in signaling requirements for PP-HEV recognition by T and B cells, and describe an unexpected level of specialization of HEVs that may allow differential, segmental control of lymphocyte subset recruitment into functionally distinct lymphoid microenvironments in vivo.

Abstract
T cell homing to peripheral lymph nodes (PLNs) is defined by a multistep sequence of interactions between lymphocytes and endothelial cells in high endothelial venules (HEVs). After initial tethering and rolling via L-selectin, firm adhesion of T cells requires rapid upregulation of lymphocyte function-associated antigen 1 (LFA-1) adhesiveness by a previously unknown pathway that activates a Galpha(i)-linked receptor. Here, we used intravital microscopy of murine PLNs to study the role of thymus-derived chemotactic agent (TCA)-4 (secondary lymphoid tissue chemokine, 6Ckine, Exodus-2) in homing of adoptively transferred T cells from T-GFP mice, a transgenic strain that expresses green fluorescent protein (GFP) selectively in naive T lymphocytes (T(GFP) cells). TCA-4 was constitutively presented on the luminal surface of HEVs, where it was required for LFA-1 activation on rolling T(GFP) cells. Desensitization of the TCA-4 receptor, CC chemokine receptor 7 (CCR7), blocked T(GFP) cell adherence in wild-type HEVs, whereas desensitization to stromal cell-derived factor (SDF)-1alpha (the ligand for CXC chemokine receptor 4 [CXCR4]) did not affect T(GFP) cell behavior. TCA-4 protein was not detected on the luminal surface of PLN HEVs in plt/plt mice, which have a congenital defect in T cell homing to PLNs. Accordingly, T(GFP) cells rolled but did not arrest in plt/plt HEVs. When TCA-4 was injected intracutaneously into plt/plt mice, the chemokine entered afferent lymph vessels and accumulated in draining PLNs. 2 h after intracutaneous injection, luminal presentation of TCA-4 was detectable in a subset of HEVs, and LFA-1-mediated T(GFP) cell adhesion was restored in these vessels. We conclude that TCA-4 is both required and sufficient for LFA-1 activation on rolling T cells in PLN HEVs. This study also highlights a hitherto undocumented role for chemokines contained in afferent lymph, which may modulate leukocyte recruitment in draining PLNs.

Abstract
Although activation of lymphocytes is known to be associated with profound changes in homing behavior, it remains unclear how activation alters migration of gut-derived lymphocytes in lymphoid and nonlymphoid organs. The objectives of this study were 1) to compare migration of naive and concanavalin A (ConA)-activated T lymphocytes into the gut mucosa, spleen, and liver and 2) to define the role of specific adhesion molecules in this homing process. Fluorescently labeled T lymphocytes collected from rat intestinal lymph were injected into the jugular vein, and the kinetics of appearance of the infused lymphocytes were monitored in ileal Peyer's patches, spleen, and liver. The migration of naive and ConA-activated T lymphocytes into microvessels were compared using an intravital microscope. ConA stimulation significantly increased the rolling velocity of T lymphocytes in postcapillary venules of Peyer's patches, and ConA-stimulated lymphocytes exhibited a loss of the selective adherence properties in Peyer's patches that is normally observed with naive T cells. ConA activation also suppressed the accumulation of T cells in the spleen. On the other hand, the adherence of T cells to hepatic sinusoidal endothelium was significantly increased after ConA activation, especially in the periportal area, and this increase was attenuated by an anti-intercellular adhesion molecule (ICAM)-1 antibody. Flow cytometry analysis revealed a decline in L-selectin expression and an increase in CD11a expression and ICAM-1 on the surface of ConA-treated T cells. In conclusion, activation of gut-derived T lymphocytes with ConA significantly alters their migration path, with a diminished localization to Peyer's patches and spleen and a preferential accumulation in hepatic sinusoids. This altered migration pattern likely results from changes in the expression of leukocyte adhesion molecules such as L-selectin and CD11a.

Abstract
BACKGROUND & AIMS Although nitric oxide (NO) is known to influence the recruitment of neutrophils in inflamed tissue, its role in lymphocyte-endothelial cell interactions remains poorly understood. The objectives of this study were to assess the effects of NO synthesis inhibition on T-lymphocyte migration in microvessels of rat small intestine and to define the role of adhesion molecules in this process. METHODS T lymphocytes collected from rat intestinal lymph were labeled with carboxyfluorescein diacetate succinimidyl ester and injected into the jugular vein of recipient rats. The migration of T lymphocytes into normal and NG-nitro-L-arginine methyl ester (L-NAME)-treated intestinal microvessels was monitored by using an intravital microscope. RESULTS L-NAME significantly increased rolling and adherence of lymphocytes in postcapillary venules of Peyer's patches and submucosal venules without significantly decreasing red blood cell velocity. The subsequent appearance of lymphocytes in the initial lymphatics was also accelerated by L-NAME. Anti-4-integrin antibody markedly inhibited the L-NAME-induced lymphocyte-endothelial cell interaction. Anti-P-selectin monoclonal antibody also significantly attenuated these adhesive interactions in both vascular regions. CONCLUSIONS These data suggest that NO is an important modulator of lymphocyte migration in Peyer's patches and in nonlymphoid regions of the intestine.

Abstract
It is thought that naive T cells predominantly enter lymphoid organs such as lymph nodes (LN) and Peyer's patches (PP) via high endothelial venules (HEV), whereas memory T cells migrate mainly into non-lymphoid organs. However, direct evidence for the existence of these distinct migration pathways in vivo is incomplete, and nothing is known about their migration through the different compartments of lymphoid organs. Such knowledge would be of considerable interest for understanding T cell memory in vivo. In the present study we separated naive and memory CD4+ T cells from the rat thoracic duct according to the expression of the high and low molecular weight isoforms of CD45R, respectively. At various time points after injection into congenic animals, these cells were identified by quantitative immunohistology in HEV, and T and B cell areas of different LN and PP. Three major findings emerged. First, both naive and memory CD4+ T cells enter lymphoid organs via the HEV in comparable numbers. Second, naive and memory CD4+ T cells migrate into the B cell area, although in small numbers and continuously enter established germinal centers (GC) with a bias for memory CD4+ T cells. Third, memory CD4+ T cells migrate faster through the T cell area of lymphoid organs than naive CD4+ T cells. Thus, our study shows that memory CD4+ T cells are not excluded from the HEV route. In addition, "memory" might depend in part on the ability of T cells to specifically enter the B cell area and GC and to screen large quantities of lymphoid tissues in a short time.

Abstract
We investigated the role of the T cell antigen receptor (TcR) in control of T cell migration in an in vitro system. We used T cells from transgenic mice bearing a TcR for the lysozyme peptide 48-62 bound to I-A(k) (3A9). T cells from the 3A9 TcR transgenic mice crawled on purified intercellular adhesion molecule-1 substrates, but strikingly, stopped upon interaction with the physiological ligand, i.e., the mouse I-A(k) with covalently attached hen egg white lysozyme peptide residues 48-62 complex. TcR-triggered stopping was reversible by treatment with adhesion-strengthening phorbol esters. The microtubule organizing center of stopped cells was positioned adjacent to the site of stable cell anchorage. Direct conversion of lymphocyte function associated-1 to the high-affinity conformation with antibodies also stopped T cells in a similar manner to antigen. Thus, physiological TcR engagement triggers a stop signal through lymphocyte function associated-1. We propose that the stop signal is an early and essential event in T cell activation that also will play an important role in control of T cell migration.
