Dataset Summary
Title | Identification and characterization of proteins that form the inner core Ixodes scapularis tick attachment cement layer. |
Description | Ixodes scapularis and other hard ticks are long-term blood feeders. This feeding behavior is facilitated by a tick secreted bio adhesive (tick cement) that attaches tick mouthparts to skin tissue and prevents the host from dislodging the tick from its feeding site. Understanding tick cement formation is highly sought after as its disruption will prevent tick feeding. This study describes proteins that form the inner core layer of I. scapularis tick cement as disrupting these will stop formation of the outer cortical layer. As the inner core cement layer completes forming by 24 h of attachment, we used laser capture to isolate cement from cryosections of 6 h and 24 h tick attachment sites and to distinguish between early and late inner core cement proteins. LC-MS/MS analysis identified 138 tick cement proteins (TCPs) of which 37 and 35 were unique in cement of 6 and 24 h respectively, and 66 shared proteins. The 138 TCPs are classified in 14 functional categories: cuticular protein (16%), tick specific proteins of unknown function, cytoskeletal proteins, and enzymes (at 13% each), enzymes (10%), antioxidant, glycine rich, scaffolding, heat shock, histone, histamine binding, proteases and protease inhibitors, and miscellaneous (at 3-6% each). Gene ontology analysis confirm that TCPs are enriched for bio adhesive properties. Our data offer insights into yet unknown tick cement bonding patterns and set the foundation for understanding the molecular basis of I. scapularis tick cement formation. |
