Lymph node germinal centers form in the absence of follicular dendritic cell networks. (1/1018)

Follicular dendritic cell networks are said to be pivotal to both the formation of germinal centers (GCs) and their functions in generating antigen-specific antibody affinity maturation and B cell memory. We report that lymphotoxin beta-deficient mice form GC cell clusters in the gross anatomical location expected of GCs, despite the complete absence of follicular dendritic cell networks. Furthermore, antigen-specific GC generation was at first relatively normal, but these GCs then rapidly regressed and GC-phase antibody affinity maturation was reduced. Lymphotoxin beta-deficient mice also showed substantial B cell memory in their mesenteric lymph nodes. This memory antibody response was of relatively low affinity for antigen at week 4 after challenge, but by week 10 after challenge was comparable to wild-type, indicating that affinity maturation had failed in the GC phase but developed later.  (+info)

In vivo blood flow abnormalities in the transgenic knockout sickle cell mouse. (2/1018)

The accepted importance of circulatory impairment to sickle cell anemia remains to be verified by in vivo experimentation. Intravital microscopy studies of blood flow in patients are limited to circulations that can be viewed noninvasively and are restricted from deliberate perturbations of the circulation. Further knowledge of sickle blood flow abnormalities has awaited an animal model of human sickle cell disease. We compared blood flow in the mucosal-intestinal microvessels of normal mice with that in transgenic knockout sickle cell mice that have erythrocytes containing only human hemoglobin S and that exhibit a degree of hemolytic anemia and pathological complications similar to the human disease. In sickle cell mice, in addition to seeing blood flow abnormalities such as sludging in all microvessels, we detected decreased blood flow velocity in venules of all diameters. Flow responses to hyperoxia in both normal and sickle cell mice were dramatic, but opposite: Hyperoxia promptly slowed or halted flow in normal mice but markedly enhanced flow in sickle cell mice. Intravital microscopic studies of this murine model provide important insights into sickle cell blood flow abnormalities and suggest that this model can be used to evaluate the causes of abnormal flow and new approaches to therapy of sickle cell disease.  (+info)

Segmented filamentous bacteria are potent stimuli of a physiologically normal state of the murine gut mucosal immune system. (3/1018)

Segmented filamentous bacteria (SFB) are autochthonous bacteria inhabiting the intestinal tracts of many species, including humans. We studied the effect of SFB on the mucosal immune system by monoassociating formerly germfree C3H/HeN mice with SFB. At various time points during 190 days of colonization, fragment cultures of small intestine and Peyer's patches (PP) were analyzed for total immunoglobulin A (IgA) and SFB-specific IgA production. Also, phenotypic changes indicating germinal center reactions (GCRs) and the activation of CD4(+) T cells in PP were determined by using fluorescence-activated cell sorter analyses. A second group of SFB-monoassociated mice was colonized with a gram-negative commensal, Morganella morganii, to determine if the mucosal immune system was again stimulated and to evaluate the effect of prior colonization with SFB on the ability of M. morganii to translocate to the spleen and mesenteric lymph nodes. We found that SFB stimulated GCRs in PP from day 6 after monoassociation, that GCRs only gradually waned over the entire length of colonization, that natural IgA production was increased to levels 24 to 63% of that of conventionally reared mice, and that SFB-specific IgA was produced but accounted for less than 1.4% of total IgA. Also, the proportion of CD4(+), CD45RBlow T cells, indicative of activated cells, gradually increased in the PP to the level found in conventionally reared mice. Secondary colonization with M. morganii was able to stimulate GCRs anew, leading to a specific IgA antibody response. Previous stimulation of mucosal immunity by SFB did not prevent the translocation of M. morganii in the double-colonized mice. Our findings generally indicate that SFB are one of the single most potent microbial stimuli of the gut mucosal immune system.  (+info)

Convective oxygen transport and tissue oxygen consumption in Weddell seals during aerobic dives. (4/1018)

Unlike their terrestrial counterparts, marine mammals stop breathing and reduce their convective oxygen transport while performing activities (e.g. foraging, courtship, aggressive interactions, predator avoidance and migration) that require sustained power output during submergence. Since most voluntary dives are believed to remain aerobic, the goal of this study was to examine the potential importance of the dive response in optimizing the use of blood and muscle oxygen stores during dives involving different levels of muscular exertion. To accomplish this, we designed a numerical model based on Fick's principle that integrated cardiac output (Vb), regional blood flow, convective oxygen transport (Q(O2)), muscle oxymyoglobin desaturation and regional rates of oxygen consumption (VO2). The model quantified how the optimal matching or mismatching of QO2 to VO2 affected the aerobic dive limit (ADL). We chose an adult Weddell seal Leptonycotes weddellii on which to base our model because of available data on the diving physiology and metabolism of this species. The results show that the use of blood and muscle oxygen stores must be completed at the same time to maximize the ADL for each level of VO2. This is achieved by adjusting Vb (range 19-94 % of resting levels) and muscle QO2 according to the rate of muscle oxygen consumption (VMO2). At higher values of VMO2, Vb and muscle perfusion must increase to maintain an appropriate QO2/VO2 ratio so that available blood and muscle oxygen stores are depleted at the same time. Although the dive response does not sequester blood oxygen exclusively for brain and heart metabolism during aerobic dives, as it does during forced submersion, a reduction in Vb and muscle perfusion below resting levels is necessary to maximize the ADL over the range of diving VO2 (approximately 2-9 ml O2 min-1 kg-1). Despite the reduction in Vb, convective oxygen transport is adequate to maintain aerobic metabolism and normal function in the splanchnic organs, kidneys and other peripheral tissues. As a result, physiological homeostasis is maintained throughout the dive. The model shows that the cardiovascular adjustments known as the dive response enable the diving seal to balance the conflicting metabolic demands of (1) optimizing the distribution and use of blood and muscle oxygen stores to maximize the ADL over the normal range of diving VO2 and (2) ensuring that active muscle receives adequate oxygen as VMO2 increases.  (+info)

The colonic mesenteric margin is most susceptible to injury in an experimental model of colonic ulceration. (5/1018)

BACKGROUND: Crohn's disease ileal ulcers and indomethacin-induced jejunal ulceration in the rat tend to occur in the mucosa nearest to the mesentery (mesenteric margin), an area of the bowel wall that has a critical blood supply. Mercuric chloride induces caecal and colonic ulceration in the Brown Norway rat. AIM: To examine whether the mesenteric margin is more sensitive to injury by a substance known to be vasculotoxic in the caecum and colon. METHODS: Brown Norway rats received a single subcutaneous dose of either mercuric chloride 1 mg/kg or saline. The gastrointestinal tract was examined macro- and microscopically for lesions 48 h later. The vascular anatomy of the normal rat colon and caecum was also examined using the carbon ink perfusion technique. RESULTS: Mercuric chloride induced caecal and colonic ulceration preferentially along the mesenteric margin of the bowel wall. Histologically, the lesions showed mucosal necrosis and neutrophil infiltration. There was also extensive vascular degeneration/necrosis with microaneurysm formation and extensive submucosal haemorrhage. Cellular infiltration of the vasculature was not a feature. The caecal and colonic mesenteric margins in control rats were supplied by small end arteries. CONCLUSIONS: The colonic and caecal mesenteric margins are susceptible to injury by mercuric chloride, a chemical known to induce haemorrhagic vasculopathy in the rat gastrointestinal tract. The large bowel mesenteric margin may be susceptible to injury by mercuric chloride because of the critical blood supply to that side of the bowel wall.  (+info)

Differential induction of adhesion molecule and chemokine expression by LTalpha3 and LTalphabeta in inflammation elucidates potential mechanisms of mesenteric and peripheral lymph node development. (6/1018)

Lymphotoxin (LT) is a member of the proinflammatory TNF family of cytokines that plays a critical role in the development of lymphoid tissue. It has previously been reported that the presence of the LTalpha transgene under the control of the rat insulin promoter results in inflammation at the sites of transgene expression. LTalpha transgene expression results in expression of the adhesion molecules VCAM, ICAM, peripheral node addressin (a marker of peripheral lymph nodes), and mucosal addressin cellular adhesion molecule (a marker of mucosal lymphoid tissue, including mesenteric lymph nodes). In this study to determine the mechanisms by which LT promotes inflammation and lymphoid tissue organization, we analyzed the regulation of expression of adhesion molecules and chemokines in LT transgenic mice. The results demonstrate that LTalpha3 induces expression of the adhesion molecules VCAM, ICAM, and mucosal addressin cellular adhesion molecule as well as the chemokines RANTES, IFN-inducible protein-10, and monocyte chemotactic protein-1, while LTalphabeta is required for the induction of peripheral node addressin that may contribute to the recruitment of L-selectinhigh CD44low naive T cells. These data provide candidate mediators of LT-induced inflammation as well as potential mechanisms by which LTalpha and LTalphabeta may differentially promote the development of mesenteric and peripheral lymph nodes.  (+info)

Transmesenteric hernia after laparoscopic-assisted sigmoid colectomy. (7/1018)

BACKGROUND AND OBJECTIVES: Laparoscopic-assisted surgery has been applied for a variety of colonic surgery. The objective of this paper is to demonstrate a possible and avoidable complication of laparoscopic colonic surgery. CASE PRESENTATION: A 47-year-old woman underwent gasless laparoscopic-assisted sigmoid colectomy. On the 20th postoperative day, she developed bowel obstruction. Decompression with a long tube failed to resolve the bowel obstruction. Open laparotomy was performed. Abdominal exploration revealed a loop of the small bowel incarcerated in the mesenteric defect caused by the previous operation. Adhesiolysis was performed, and the postoperative course was uneventful. DISCUSSION: Despite technical difficulty, complete closure of the mesentery after bowel resection is strongly recommended for prevention of transmesenteric incarcerated hernia after laparoscopic surgery.  (+info)

Vascular endothelial growth factor attenuates leukocyte-endothelium interaction during acute endothelial dysfunction: essential role of endothelium-derived nitric oxide. (8/1018)

Vascular endothelial growth factor (VEGF) is an endothelium-specific secreted protein that induces vasodilation and increases endothelial release of nitric oxide (NO). NO is also reported to modulate leukocyte-endothelium interaction. Therefore, we hypothesized that VEGF might inhibit leukocyte-endothelium interaction via increased release of NO from the vascular endothelium. We used intravital microscopy of the rat mesenteric microcirculation to measure leukocyte-endothelium interactions 2, 4, and 24 h after systemic administration of VEGF to the rat (120 microg/kg, i.v., bolus). Superfusion of the rat mesentery with either 0.5 U/ml thrombin or 50 microM L-NAME consistently increased the number of rolling, adhering, and transmigrated leukocytes (P<0.01 vs. control mesenteries superfused with Krebs-Henseleit buffer). At 4 and 24 h posttreatment, VEGF significantly attenuated thrombin-induced and L-NAME-induced leukocyte rolling, adherence, and transmigration in rat mesenteric venules. In addition, adherence of isolated rat PMNs to thrombin-stimulated mesenteric artery segments in vitro was significantly reduced in mesenteric arteries isolated from VEGF-treated rats (P<0.001 vs. control rats). Direct measurement of NO demonstrated a threefold increase in basal NO release from aortic tissue of rats injected with VEGF, at 4 and 24 h posttreatment (P<0. 01 vs. aortic tissue from control rats). Finally, systemic administration of VEGF to ecNOS-deficient mice failed to inhibit leukocyte-endothelium interactions observed in peri-intestinal venules. We concluded that VEGF is a potent inhibitor of leukocyte-endothelium interaction, and this effect is specifically correlated to augmentation of NO release from the vascular endothelium.--Scalia, R., Booth, G., Lefer, D. J. Vascular endothelial growth factor attenuates leukocyte-endothelium interaction during acute endothelial dysfunction: essential role of endothelium-derived nitric oxide.  (+info)

Guanylyl cyclase C (GC-C) is a member of a family of enzymes that metabolize GTP to cGMP and was first identified as a receptor for heat-stable enterotoxin. Guanylin (GNY) has since been identified as an endogenous ligand for GC-C in the intestine of several mammalian species. The GNY/GC-C system regulates ion transportation and pH in the mucosa. Recently, it was reported that GC-C and GNY are involved in lipid metabolism in rat mesenteric adipose tissue macrophages. To examine the role of GC-C and GNY in lipid metabolism in cattle, we used a bovine mesenteric adipocyte primary culture system and a coculture system for bovine adipocytes and GNY-/GC-C-expressing macrophages. Fat droplets were observed to accumulate in bovine mesenteric adipocytes cultured alone, whereas few fat droplets accumulated in adipocytes indirectly cocultured with macrophages. We also observed that GC-C was present in bovine mesenteric adipose tissue, and that fat droplet accumulation decreased after in vitro GNY ...

N2 - The examination of lymph nodes in colorectal cancer is a critical procedure for determining the stage, which determines prognosis and need for adjuvant therapy. The current recommendation is to harvest at least 12 lymph nodes by conventional manual node dissection (MND). Recent studies have suggested that all lymph nodes in mesenteric tissue should be retrieved using a special method such as the entire submission of residual mesenteric tissue (ESMT) after MND. We investigated the efficacy of ESMT with its potential impact on the pN stage. After an MND in 48 consecutive ...

Below the level of the upper part of the duodenum the ventral mensentery is wanting; only the dorsal mesentery occurs. So long as the intestine is a straight tube the length of the intestinal edge of this mesentery is practically equal to that of its dorsal attached edge. The intestine, however, increasing in length much more rapidly than the abdominal walls, the intestinal edge of the mesentery soon becomes very much longer than the attached edge, and when the intestine grows out into the umbilical ccelom the mesentery accompanies it (Fig. 198). As the coils of the intestine develop, the intestinal edge of the mesentery is thrown, into corresponding folds, and on the return of the intestine to the abdominal cavity the mesentery is thrown into a somewhat funnel-like form by the twisting of the intestine to form its primary loop (Fig. 199). All that portion of the mesentery which is attached to the part of the intestine which will later become the jejunum, ileum, ascending and transverse colon, ...

Mathematicians and biologists at Harvard explain why vertebrate intestines are so predictably loopy. Between conception and birth, the human gut grows more than two meters long, looping and coiling within the tiny abdomen. Within a given species, the developing vertebrate gut always loops into the same formationhowever, until now, it has not been clear why.. Using a combination of experimental observations, biological and biophysical manipulations, theory, and computation, researchers at Harvard have shown that a simple balance of forces determines the form of the gut.. The finding may shed light on how the gut has been able to evolve to accommodate changes in diet.. The interdisciplinary research, published in the August 4th issue of Nature, demonstrates that differences in growth rates between the gut tube and the neighboring mesenteric tissue force the tube to coil, regardless of the space constraints.. One might think that the gut tube coils because it is restricted by the size of the ...

Idiopathic sclerosing mesenteritis (ISM) or mesenteric panniculitus is a rare disease of the small intestine, characterized by chronic inflammation and eventual fibrosis of the mesentery. It has also been called mesenteric lipodystrophy, or retractile mesenteritis. Sclerosing mesenteritis may present with no or nearly no signs or symptoms, but many people have chronic and severe pain in the abdomen as the most common chief complaint. Other people have chronic problems with bowel movements, resulting in diarrhea, bloating, gas, and cramping which can range from severe to mild. The disorder is identified by histopathology showing fat necrosis, fibrosis and chronic inflammation of the small intestine. Examination of the mesentery may indicate a solitary mass, but diffuse mesentery thickening is common. It often mimics other abdominal diseases such as pancreatic or disseminated cancer. CT scanning is important for making the initial diagnosis. Several causes of sclerosing mesenteritis have been ...

Background Diet plays a role on the development of the immune system, and polyunsaturated fatty acids can modulate the expression of a variety of genes. Human milk contains conjugated linoleic acid (CLA), a fatty acid that seems to contribute to immune development. Indeed, recent studies carried out in our group in suckling animals have shown that the immune function is enhanced after feeding them with an 80:20 isomer mix composed of c9,t11 and t10,c12 CLA. However, little work has been done on the effects of CLA on gene expression, and even less regarding immune system development in early life. Results The expression profile of mesenteric lymph nodes from animals supplemented with CLA during gestation and suckling through dams milk (Group A) or by oral gavage (Group B), supplemented just during suckling (Group C) and control animals (Group D) was determined with the aid of the specific GeneChip® Rat Genome 230 2.0 (Affymettrix).

Sclerosing mesenteritis (SM) is sometimes used as an umbrella-term for idiopathic inflammatory conditions in the mesentery. Mesenteric panniculitis (MP) is a radiological finding and its relation to clinical SM is not fully understood. The aims of this study were to determine whether any correlation could be found between the radiological findings and the clinical disease course. Patients observed due to idiopathic inflammation of the mesentery were identified. If SM could be verified histologically or MP radiologically, the patients were included in this descriptive retro perspective study. Typical radiological changes were observed in 27 patients. A majority (23/27) of these patients had mild to moderate symptoms. This group with typical radiology was labelled MP. Four patients were included due to histologically verified disease but had uncharacteristic radiology involving multiple compartments of the abdomen. All four had marked systemic inflammation, fever and fluctuating radiologic findings. Three

In the present study, to investigate diagnosis and treatment of strangulated intestinal obstruction caused by mesentery vein thrombosis on account of portal hypertension, the data in twelve patients with this disease from 1998 to 2008 were analyzed. All patients presented abdominal pain and vomiting and were confirmed strangulated intestinal obstruction caused by mesentery thrombosis with operation. In this group, nine patients underwent part of small intestine excision, and three patients underwent open-closed operation because of the whole small intestine necrosis caused by intensive mesentery thrombosis. Five patients died after operation. The diagnosis of strangulated intestinal obstruction caused by mesentery thrombosis was difficult because of the slow disease processes and severe outcomes. It is necessary to take some measures to get over the dangers duration after operation.

I thought I would start a discussion for patients with Mesenteric Panniculitis. From what I know, this auto-immune disorder has three stages to it, each with differing names (Mesenteric Panniculitis, Schlerosing Mesenteritis, Retractile Mesenteritis). Typically, this appears to be in older individuals with some other under-lying problem (Lymphoma, tumor, diverticulitis).I […]

Summary. Mesenteric panniculits, also known as sclerosing mesenteritis, belongs to a spectrum of rare diseases of the fatty (adipose) tissue of the mesentery. Mesenteric panniculitis is characterized by fat degeneration and necrosis, chronic inflammation, and at times, scarring and fibrosis of fatty tissue within the mesentery. This inflammatory and at times progressive condition is most likely on the spectrum of autoimmune disorders.. The mesentery is a fold of tissue within the peritoneum that supports and attaches the small and large intestines to the walls of the abdomen. The mesentery contains fat, blood vessels, lymphatic tissue, lymphatic vessels and other forms of connective tissue. The peritoneum is a membrane that lines the abdominal cavity and covers the abdominal organs. The mesentery of the small intestine is most often affected in mesenteric panniculitis. Although the exact cause of mesenteric panniculitis remains unknown, the disease has been associated with a variety of other ...
Continuum models of the lymphatic system are scarce. As mentioned previously, Macdonald et al. [45] refined Reddys mathematical model by including two terms in the transmural pressure equation: a tension term and a damping term. Moreover, spatial averages of the pressure were not assumed, thus retaining the continuum nature of the governing equations. Two notable differences are that the contraction of the vessel wall was modelled by a change in Youngs modulus rather than an active stress added to the stress state of the material, and it was assumed that lymphangions do not have a refractory period, as in the work by Reddy et al. [75]. Data for parameters such as the Young modulus and damping were derived by experiments on bovine mesenteric lymphatics, although the properties measured had a very large variation owing to uncertainties in vessel diameter and wall thickness measurements.4 The Young modulus was found to be 1.2 ± 0.7 kPa; a quite large variation, possibly even larger than the ...
Cytokines (IL-6, IL-10 and TNF-α) are increased after exhaustive exercise in the rat retroperitoneal (RPAT) and mesenteric adipose tissue (MEAT) pads. On the other hand, these cytokines show decreased expression in these depots in response to a chronic exercise protocol. However, the effect of exercise with overload combined with a short recovery period on pro- and anti-inflammatory cytokine expression is unknown. In the present study, we investigated the regulation of cytokine production in the adipose tissue of rats after an overtraining-inducing exercise protocol. Male Wistar rats were divided into four groups: Control (C), Trained (Tr), Overtrained (OT) and recovered overtrained (R). Cytokines (IL-6, TNF-α and IL-10) levels and Toll Like Receptor 4 (TLR4), Nuclear Factor kBp65 (NF-kBp65), Hormone Sensitive Lipase (HSL) and, Perilipin protein expression were assessed in the adipose tissue. Furthermore, we analysed plasma lipid profile, insulin, testosterone, corticosterone and endotoxin levels, and

IL-17-expressing CD4+ T lymphocytes (Th17 cells) naturally reside in the intestine where specific cytokines and microbiota, such as segmented filamentous bacteria (SFB), promote their differentiation. Intestinal Th17 cells are thought to initially differentiate in the GALT and/or mesenteric lymph nodes upon Ag encounter and subsequently home to the lamina propria (LP) where they mediate effector functions. However, whether GALT and/or mesenteric lymph nodes are required for intestinal Th17 differentiation as well as how microbiota containing SFB regulate Ag-specific intestinal Th17 cells remain poorly defined. In this study, we observed that naive CD4+ T cells were abundant in the intestinal LP prior to weaning and that the accumulation of Th17 cells in response to microbiota containing SFB occurred in the absence of lymphotoxin-dependent lymphoid structures and the spleen. Furthermore, the differentiation of intestinal Th17 cells in the presence of microbiota containing SFB was dependent on MHC ...
Immune tissues are known to be innervated by the sympathetic nervous system, but little is known of what directs the innervation to specific tissue compartments. This report examines the sympathetic innervation of immune tissues in transgenic mice that overexpress nerve growth factor (NGF) in skin and other epithelial structures. NGF transgenic mice exhibited dramatic hyperinnervation in the splenic marginal zone, and the medulla and capsule of peripheral lymph nodes. In contrast, the transgenic mesenteric lymph nodes showed no hyperinnervation. This difference correlated with the location of these nodes; peripheral lymph nodes drain skin where the transgene was expressed while mesenteric lymph nodes drain non-transgene-expressing structures. In addition, the level of innervation correlated with the level of NGF peptide content as assayed by ELISA (3- and 13-fold increase in transgenic spleen and axillary lymph nodes, respectively; no increase in mesenteric nodes) and immunocytochemistry. RT-PCR ...

Protein kinase G (PKG) is activated by nitric oxide (NO)-induced cGMP binding or alternatively by oxidant-induced interprotein disulfide formation. We found preactivation with cGMP attenuated PKG oxidation. 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) blockade of cGMP production increased disulfide PKG to 13±2% and 29±4% of total in aorta and mesenteries, respectively. This was potentially anomalous, because we observed 2.7-fold higher NO levels in aorta than mesenteries; consequently, we had anticipated that ODQ would induce more disulfide in the conduit vessel. ODQ also constricted aorta, whereas it had no effect on mesenteries. Thus, mesenteries, but not aorta, can compensate for loss of NO-cGMP by recruiting disulfide activation of PKG. Mechanistically, this is explained by loss of cGMP allowing disulfide formation in response to basal oxidant production. Why aorta treated with ODQ generated less PKG disulfide that is insufficient to induce vasoconstriction was unclear. One potential ...

  • The dorsal mesentery of stomach and duodenum is wide and topographically complex due to strong and asymmetric growth of the stomach. (edu.au)
  • The root of the mesentery extends from the duodenojejunal flexure to the ileocaecal junction. (wikipedia.org)
  • The line of attachment of the root of the mesentery is oblique. (anatomyexpert.com)
  • Due to the range of abdominal organs the mesentery envelopes, the root is long, narrow and has an oblique orientation, from the left side of the L2 vertebra to the right sacroiliac junction roughly. (teachmeanatomy.info)
