title: Identification of putative innate immune related genes from a cell line of the mosquito Aedes albopictus following bacterial challenge.
abstract: We report identification of putative innate immune related genes from a cell line of the mosquito Aedes albopictus challenged with heat-killed bacteria. Using a subtractive hybridization and sequencing approach, we analyzed a total 309 expressed sequence tags (ESTs) which clustered in 40 contigs. Thirty-five percent of genes yielded homology to known immune genes corresponding to antimicrobial peptides (AMPs), pathogen-associated molecular patterns, protease and immune signaling cascades. Interestingly, most of the genes have not been previously described from this mosquito and thus represent a class of novel immune genes. Further, 25% sequences did not match to any known species in the non-redundant databases, appear to be specific to the mosquito A. albopictus and merit further study.
