2013-4-1 · 1. Introduction. Lymphoid aggregates, whether benign or malignant, are a relatively uncommon finding in bone marrow biopsy specimens. In many cases, identifying the neoplastic nature of the aggregates by morphology can be easily achieved; however, in instances when multiple aggregates are identified with no documented history of lymphoma, such distinction

The GI tract lymphoid aggregate disruption is of clinical relevance given that these aggregate locations function as viral reservoirs during HIV-1 infection. These lymphoid aggregates also contain CD4+T cells that express a4B7 and offer a potential and important target for an anti-a4B7D therapeutic approach for HIV-1.

Aims Colonic inflammation is followed by regeneration supported by bone marrow-derived cells (BMDCs) including multipotent cells. They migrate to the colonic epithelial layer and may transdifferentiate into epithelial-like cells or keep their stem cell characteristics and produce progenies. The aim was to study the role of lymphoid aggregates in the migration and

Glutathione is a nonenzymatic antioxidant synthesized by most animal cells and is depleted in inflammatory bowel disease. The effects of glutathione depletion on intestinal histology and inhibitory neurochemicals was examined in a mouse model. Glutathione depletion in A/J mice involved inhibition of γ-glutamylcysteine synthetase using l-buthionine-(S,R)-sulfoximine (BSO)

2018-6-14 · Herein, we present the first human study of anti-α4β7 therapy in a cohort of HIV-1 infected subjects with mild inflammatory bowel disease. α4β7+ gut homing CD4+ T cells are early viral targets and contribute to HIV-1 pathogenesis, likely by seeding the gastrointestinal (GI) tract with HIV. Although, simianized anti-α4β7 monoclonal antibodies (Mab) have shown promise in
