Detailed explanation-1: -Mast cells play an important role in how the immune system responds to certain bacteria and parasites and they help control other types of immune responses. They contain chemicals such as histamine, heparin, cytokines, and growth factors.
Detailed explanation-2: -Mast cells synthesize and secrete histamine, proteases, prostaglandin D2, leukotrienes, heparin, and a variety of cytokines, many of which are implicated in CVD (36, 93–100). Furthermore, mast cells enhance endothelial inflammatory responses through upregulation of innate immune mechanisms (101, 102).
Detailed explanation-3: -Mast Cells are found close to small blood vessels in loose connective tissue.
Detailed explanation-4: -In addition, mast cells release proteases and heparin which release pro-angiogenic factors that bind to heparin. Histamine, released by mast cells, induces permeability of the microvasculature that also induces angiogenesis.
