Update publication information. Tick saliva, an essential chemical secretion of the tick salivary gland, is indispensable for tick survival owing to the physiological influence it exerts on the host defense mechanisms via the instrumentality of its cocktail of pharmacologically active molecules (proteins and peptides).Here, we performed a phosphoproteomic analysis of Haemaphysalis longicornis tick saliva via LC-MS/MS. A total of 262 phosphorylated tick saliva proteins were identified, and were subjected to functional annotation/enrichment analysis. Cellular and metabolic process terms accounted for the largest proportion of the saliva proteins, with the participation of these proteins in vital intracellular and extracellular transport-oriented processes such as vesicle-mediated transport, exocytic process, cell adhesion, and movement of cell or subcellular component. “Endocytosis”, “Protein processing in endoplasmic reticulum”, and “Purine metabolism” were the most significantly enriched pathways. The knockdown (RNAi) of Tudor domain-containing protein (TCP), actin depolymerizing factors (ADF), programmed cell death protein (PD), and serine/threonine-protein kinase (SPK) resulted in the dissociation of collagen fibers and pilosebaceous unit, increased inflammatory infiltrates/granulocytes (possibly heterophyles), and the depletion of the epithelium.
