Inflammation

Humoral Response

Detailed explanation-1: -Neutrophils. These cells are most abundant and effective during the inflammation and phagocytosis processes.
Detailed explanation-2: -It is now recognized that inflammation induced by microbial infection and tissue damage is an essential mechanism of innate immune response.
Detailed explanation-3: -DAMPs AND PAMPs TRIGGER THE INNATE IMMUNE RESPONSE DAMPs are endogenous molecules normally found in cells that get released during necrosis and contribute to sterile inflammation.
Detailed explanation-4: -Innate immunity can be viewed as comprising four types of defensive barriers: anatomic (skin and mucous membrane), physiologic (temperature, low pH and chemical mediators), endocytic and phagocytic, and inflammatory. Table 1 summarizes the non-specific host-defense mechanisms for each of these barriers.
Detailed explanation-5: -The innate immune system can be categorized into three defense mechanisms: (1) physical barriers, (2) cellular components, and (3) humoral responses (15). As will be discussed, the functions of these defense mechanisms are highly conserved between fish and mammals.
