摘要: Abstract The salivary glands are vital to the biological success of ixodid ticks and major route for pathogen transmission. Important functions include absorption water vapor from unsaturated air by free-living ticks, excretion excess fluid blood meal concentration, secretion bioactive protein lipid compounds during tick feeding. Fluid is controlled nerves. Dopamine neurotransmitter at neuroeffector junction regulating via adenylate cyclase an increase in cellular cAMP. also affects release arachidonic acid which subsequently converted prostaglandins. Prostaglandin E2 (PGE2) secreted extremely high levels into saliva export host where it impacts physiology. Additionally, PGE2 has autocrine or paracrine role within gland itself interacts with a receptor induce (exocytosis) proteins phosphoinositide signalling pathway Ca2+. Regulation been extensively studied, but little known about mechanism secretion. Continuing advances physiology will be made as key regulatory secretory purified and/or their genes cloned sequenced.
