Stromal microenvironments of bone marrow, lymph nodes, and spleen have been shown to be able to regulate immune cell differentiation and function. Our previous studies demonstrate that splenic stroma could drive mature dendritic cells (DC) to further proliferate and differentiate into regulatory DC subset that could inhibit T cell response via NO. However, how splenic stroma-educated regulatory...

splenic hamartoma is an unusual accidental finding with non-neoplastic feature that may be incidentally diagnosed because of its compression effect on surrounding organs. the predominant pathological feature leading diagnosis is circumscribed, un-encapsulated bulging nodules with focal fibrosis or cyst. the histopathological feature of splenic hamartoma is the positivity for cd8, and occasional...

The factors regulating growth and patterning of the spleen are poorly defined. We demonstrate here that spleens from B cell-deficient mice have 10-fold reduced expression of the T zone chemokine, CCL21, a threefold reduction in T cell and dendritic cell (DC) numbers, and reduced expression of the T zone stromal marker, gp38. Using cell transfer and receptor blocking approaches, we provide evide...

purpose: to investigate confocal scan features of corneal subbasal nerve plexus and epithelial dendritic cells in herpes simplex keratitis (hsk) as compared to acanthamoeba keratitis (ak). methods: confocal scan records of patients with clinical and confocal microscopic features compatible with hsk and ak as well as confocal scan records of normal participants were reviewed. the density and mor...

Nanomedicine, the medical application of nanotechnology, promises a seemingly limitless range of applications from drug delivery to adjuvants and therapeutics. Our current research is focused on natural polymer-based liposome adjuvants. With the aim of inducing protective and long-lasting immunity, the immunological adjuvant activity of Rehmannia glutinosa polysaccharide liposome (RGPL) was inv...

BACKGROUND Obesity has become a global challenge for public health. It has been reported that obesity is associated with chronic inflammation. However, the mechanism for the chronic inflammation contributes to obesity remains elusive. METHODOLOGY/PRINCIPAL FINDINGS In our study, we found a novel CD11c+ dendritic cell subset existed in murine adipose tissues which was immature phenotype. Moreo...
