An image of the spleen in the human body. Also shows the red and white pulp regions. Splenocytes are spleen cells and consist of leukocytes like B and T cells, dendritic cells, and macrophages. [2] The spleen is split into red and white pulp regions with the marginal zone separating the two areas. The red pulp is involved with filtering blood ...
The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen. The Kupffer cells of the liver and tissue histiocytes are also part of the MPS. The mononuclear phagocyte system and the monocyte macrophage system refer to two different entities, often mistakenly understood as one.
The spleen (from Anglo-Norman espleen, ult. from Ancient Greek σπλήν, splḗn) [1] is an organ found in almost all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (erythrocytes) and the immune system. [2]
The cords of Billroth (also known as splenic cords or red pulp cords) are found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages.
Similar to B1 B cells, MZ B cells can be rapidly recruited into the early adaptive immune responses in a T cell-independent manner. [9] The MZ B cells are especially well-positioned as the first line of defense against systemic blood-borne antigens that enter the circulation and become trapped in the spleen. [10]
To change this template's initial visibility, the |state= parameter may be used: {{Spleen | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Spleen | state = expanded}} will show the template expanded, i.e. fully visible. This template is a navigation box relating to anatomy that provides links to ...
In anatomy the term reticuloendothelial system (abbreviated RES), often associated nowadays with the mononuclear phagocyte system (MPS), was employed by the beginning of the 20th century to denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells) from the blood circulation.
The major role of marginal zone is to trap particulate antigen from the circulation and present the antigen to the lymphocytes of the spleen. Experiments have shown that inert latex beads as well as live bacteria such as Escherichia coli and Listeria monocytogenes are trapped by the marginal zone.
