The innate immune response

Phagocytosis is a mechanism of the innate insubordinate reception. Describe trine cells who be responsible for phagocytosis and describe what triggers each to respond. Describe how cardinal other aspects of the repellent response can stir phagocytosis. What situation do scavenger cells play in initiating the adjustive resistant response?         The innate immune response reduces the workload of the adaptive immune response by preventing entry and spread of microorganisms in the body. The branch line of defense is the external body tissue layer - total skin and mucosae. The second line of defense is c solelyed into action when the starting time line of defense has been penetrated, use antimicrobial proteins and phagocytes. A phagocyte engulfs matter the way an ameba ingests a food particle. Three cells that ar responsible for phagocytosis argon monocytes, neutrophils, and eosinophils. The major phagocytes ar macrophages, which derive from fre sh blood cells called monocytes that kick in the bloodstream, enter the tissues, and develop into macrophages. When chemicals released by immune cells stimulate them, additional enzymes atomic number 18 activated that produce the respiratory burst, an event that liberates a flood of free radicals that have unbendable cell-killing ability. Monocytes take active 12 hours to differentiate and there are a chaw of them. Neutrophils become phagocytic on merginging pathogenic materials in the tissues.

Neutrophils are small but numerous and plus during acute transmission system (especially bacterial), secreting enzymes and producing antibiotic-like chemi! cals called defensins, that pierce the pathogens membrane and destroy the neutrophils in the process. Eosinophils are decrepit phagocytic and are fewer, but they are important in defending the body against parasitic worms. When they encounter parasitic worms, the eosinophils let go of the contents of their large cytoplasmic granules all over their prey. devil other aspects of the immune response that can enhance phagocytosis are adherence and opsonization.
