Question
histamines, kinins, and prostaglandins produced by mucous membranes include produced by skin innate (nonspecific) defenses epithelia include that fight pathogens collectively called that help block viral interferons -within body tissues are internal defenses (second line of defense) replication utilize that induce apoptosis of cells utilize keratin and sebumm -infected or cancerous mucin, acid, lysozymes and defensins that involve phagocytosis- of pathogens utilize that resist entry of are collectively called natural killer cells -pathogens into the body neutrophils monocytes, and macrophages -that trigger a fever utilize pyrogens that trigger local hyperemia, pain, and edema utilize surface barriers (first line of defense)Explanation / Answer
1 histamine is an organic nitrogenous compound involved in local immune response as well as physiological function. Immune receptors are protein situated in various part of the body with histamine to produce a specific effect on organisms. The four known receptor are H1-H4. Histamine is a major mediator in allergic diseases, and has multiple effects that are mediated by specific surface receptor on target cell.
2. Kinins and prostaglandin are families of highly active substances naturally present in tissues. Kinins are plasma protein that increase vascular permeability interact with prostaglandin to cause pain and smooth muscle contraction and to increase migration of white blood cells during inflammatory process.kinins are activated by very small damage involving increased by vascular permeability or activation of cloning activity.
3. In response to viral infection, many organisms mount a remarkable defense known as immune response. This response to viral infection consist of an innate or non specific components. Macrophages also mediate innate immune response directly and make curical contribution to the effector phase of the adaptive immune response. B cells contribute to adaptive immunity by presenting peptides from antigens they have ingested and by secreting antibody.
