What are the macrophages in the spleen called?

Spleen autofluorescent cells are macrophages and represent the red pulp macrophages of the spleen. Flow cytometry stainings on monocytes in the spleen, blood monocytes, spleen autofluorescent cells, M-CSF, and GM-CSF cultured monocyte-derived macrophages.

Is phagocytosis a function of the spleen?

Phagocytosis. One of the spleen’s most important functions is phagocytosis. The spleen is a component of the reticuloendothelial system. The splenic phagocytes include reticular cells, free macrophages of the red pulp, and modified reticular cells of the ellipsoids.

Does spleen contain macrophages?

The spleen hosts all major types of mononuclear phagocytes, including macrophages, DCs and monocytes.

What is splenic phagocytosis?

Splenic MΦs have two main protective activities during blood-borne infections. The first and most well characterized is phagocytosis and elimination of pathogens from circulation. However, beyond the task of eliminating blood-borne pathogens, splenic MΦs can play a prominent role in immune system activation.

What type of cells are found in the spleen?

The white pulp of the spleen contains typical lymphoid elements, such as plasma cells, lymphocytes, and lymphatic nodules, called follicles in the spleen. Germinal centres in the white pulp serve as the sites of lymphocyte production.

How are macrophages isolated?

Through the use of flow cytometry, these cells can be identified and sorted from a heterogeneous population for further analysis. Monoclonal antibodies used to characterize specific target cell designations are chosen based upon the ability to distinguish macrophages from other hematopoietic cells.

What types of cells are found in the white pulp of the spleen and in the red pulp of the spleen?

Both white and red pulp contains lymphocytes and immune cells called macrophages. These cells dispose of antigens, dead cells, and debris by engulfing and digesting them. While the spleen functions chiefly to filter blood, it also stores red blood cells and platelets.

Does the spleen produce macrophages?

What types of cells are present in the spleen?

The white pulp of the spleen contains typical lymphoid elements, such as plasma cells, lymphocytes, and lymphatic nodules, called follicles in the spleen.

Do M2 macrophages Phagocytose?

These results are consistent with reports showing that M2 macrophages have higher phagocytic activity than M1 macrophages [35, 36].

How many types of macrophages are there in the spleen?

Macrophage heterogeneity in the spleen has been long documented, with four subsets populating the different splenic compartments. The diverse environments on the splenic compartments determine their varied phenotype and functions. In the white pulp, highly phagocytic macrophages contribute to the generation of the immune response.

What determines the phenotype of macrophages in the splenic compartments?

The diverse environments on the splenic compartments determine their varied phenotype and functions. In the white pulp, highly phagocytic macrophages contribute to the generation of the immune response. The marginal zone contains two populations of macrophages, which also contribute to the immune response.

Where are large phagocytes found in the body?

These large phagocytes are found in essentially all tissues, where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system.

What is the role of phagocytosis in the pathogenesis of arteriosclerosis?

However, as macrophages have the ability to present antigens to T cells and function as effectors for cell-mediated immunity, it is known that they affect the development of infectious diseases, cancers, and chronic inflammatory diseases such as arteriosclerosis. Additionally, phagocytosis plays a critical role in that process.
