The professional phagocytes include many types of white blood cells (such as neutrophils, monocytes, macrophages, mast cells, and dendritic cells). [8] The main difference between professional and non-professional phagocytes is that the professional phagocytes have molecules called receptors on their surfaces that can detect harmful objects ...
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
Neutrophils are a type of phagocytic white blood cell and part of innate immunity. More specifically, they form the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. [1] Their functions vary in different animals. [2] They are also known as neutrocytes, heterophils or polymorphonuclear leukocytes.
This is a list of immune cells, also known as white blood cells, white cells, leukocytes, or leucocytes. They are cells involved in protecting the body against both infectious disease and foreign invaders .
A cell that performs phagocytosis is called a phagocyte. The engulfing of a pathogen by a phagocyte. In a multicellular organism's immune system, phagocytosis is a major mechanism used to remove pathogens and cell debris. The ingested material is then digested in the phagosome.
[59] [60] [61] These early-invading, phagocytic macrophages reach their highest concentration about 24 hours following the onset of some form of muscle cell injury or reloading. [62] Their concentration rapidly declines after 48 hours. [60] The second group is the non-phagocytic types that are distributed near regenerative fibers.
A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei.
Basophils: Basophils are white blood cells that are similar to mast cells in having vasoactive agents released in response to an allergen. Monocytes: Monocytes are white blood cells that will give rise to all the phagocytes of the mononuclear phagocytic system (see Ross et al., pg. 110, and Table 5.4, pg. 112).
