Immune Profiling of Human Gut-Associated Lymphoid Tissue ...

Structure. The gut-associated lymphoid tissue lies throughout the intestine, covering an area of approximately 260–300 m 2. In order to increase the surface area for absorption, the intestinal mucosa is made up of finger-like projections (), covered by a monolayer of epithelial cells, which separates the GALT from the lumen intestine and its contents.

Gut-associated lymphoid tissue (GALT) is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut.. Owing to its physiological function in food absorption, the mucosal surface is thin and acts as a permeable barrier to the interior of the body.

Lymphoid aggregates (LA) develop during the proliferative phase of the menstrual cycle in the human uterine endometrium (EM). They contain mostly CD8 + T cells and B cells. As these LA are absent immediately following menses, they may arise by division of cells resident in the EM, or by division of a limited number of precursor cells that traffic into the EM during the early proliferative ...

Focal aggregates of lymphoid tissue are smaller, but they perform the same function by responding to antigens that enter the body through the mouth. Like all lymphoid tissue in the body, oral lymphoid tissue is highly reactive and can enlarge from time to time as it "reacts" to foreign entities.

The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the circulatory system and the immune system.It is made up of a large network of lymphatic vessels, lymphatic or lymphoid organs, and lymphoid tissues. The vessels carry a clear fluid called lymph (the Latin word lympha refers to the deity of fresh water, "Lympha") towards the heart.

Additionally, macrophages are involved in the formation of lymphoid aggregates and may participate in antigen presentation and in assisting CD8 + T and B cell activation. The function of the lymphoid aggregates in the human uterus is currently unclear, but they may be involved in antigen scavenging and antibody production.

This process is believed to cause an overall thickening of the airway wall and forms the basis of airway wall remodeling . Regional lymph nodes form part of the secondary lymphoid tissue, which includes organized subepithelial aggregations of lymphocytes, such as Peyer's patches in the gut or bronchus-associated lymphoid tissue (BALT).

Lymphoid neogenesis is traditionally viewed as a pre-programmed process that promotes the formation of lymphoid organs during development. Here, the spatial organization of T and B cells in lymph nodes and spleen into discrete structures regulates antigen-specific responses and adaptive immunity following immune challenge.

The process of the development of different blood cells from HSCs to mature cells is called hematopoiesis. Lymphocytes are the cornerstone of the adaptive immune system. Commonly known as white blood cells, they derive from common lymphoid progenitors. The lymphoid lineage is primarily composed of T-cells and B-cells.

BACKGROUND AND AIMS A histopathological feature considered indicative of ulcerative colitis (UC) is the so-called basal lymphoid aggregates. Their relevance in the pathogenesis of UC is, however, unknown. We have performed a comprehensive analysis of the immune cells in these aggregates most likely corresponding to the lymphoid follicular hyperplasia also described in other colitides.

Organized lymphoid structures were visible in the stroma of many of the high-grade SIL samples as determined by immunostaining for CD4, CD20, CD8, and CD68 (Figure 1 a–d respectively). These dense cellular accumulations had a distinct morphology: the centers of the aggregates were characterized by a predominance of B cells with widely distributed CD4 + helper T cells and macrophages.
