Sneezing and itching during the early response to allergen provocation involve the nervous system. Unilateral intranasal antigen challenge experiments.
The complement system is an important effector of both the innate and adaptive immune responses. It consists of more than 25 plasma and cell-surface proteins.
The antibodies (immunoglobulins) secreted by activated B cells are glycoproteins composed of polypeptide (82% to 96%) and carbohydrate (4% to 18%). Immunoglobulin.
Mucosal surfaces and skin encounter the environment and possess an immune system capable of responding to pathogens and foreign antigens. The mucosal immune.
Eosinophils are derived from colony-forming unit–eosinophil (CFU-Eo), a progenitor that differentiates into an eosinophilic myeloblast, promyelocyte,.
