Eosinophils are also involved in many other biological processes, including postpubertal mammary gland development, oestrus cycling, allograft rejection and neoplasia. [21] They have also been implicated in antigen presentation to T cells. [22] Eosinophils are responsible for tissue damage and inflammation in many diseases, including asthma.
Eosin is an acidic dye for staining cell cytoplasm, collagen, and muscle fibers. [1] [2] Eosinophilic describes the appearance of cells and structures seen in histological sections that take up the staining dye eosin. [2] Such eosinophilic structures are, in general, composed of protein. [3]
Historically, white blood cells were classified by their physical characteristics (granulocytes and agranulocytes), but this classification system is less frequently used now. Produced in the bone marrow, white blood cells defend the body against infections and disease. An excess of white blood cells is usually due to infection or inflammation.
Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.
Thus, the term mucosa or mucous membrane refers to the combination of the epithelium and the lamina propria. [1] The connective tissue of the lamina propria is loose and rich in cells. The cells of the lamina propria are variable and can include fibroblasts, lymphocytes, plasma cells, macrophages, eosinophilic leukocytes, and mast cells. [2]
The T cell then travels throughout the body in search of cells where the MHC I receptors bear this antigen. When an activated T cell contacts such cells, it releases cytotoxins, such as perforin, which form pores in the target cell's plasma membrane, allowing ions, water and toxins to enter.

Eosinophil cationic protein (ECP) also known as ribonuclease 3 is a basic protein located in the eosinophil primary matrix. [4] In humans, the eosinophil cationic protein is encoded by the RNASE3 gene. [5] ECP is released during degranulation of eosinophils. This protein is related to inflammation and asthma because in these cases, there are ...
