Identification of a HSP14-3-3 in Setaria cervi and its cross-reactivity with W. bancrofti infected human sera.

AIM Identification of a 29 kDa heat stress protein in filarial parasite Setaria cervi and evaluation of its diagnostic potential against lymphatic filariasis. METHODS AND RESULTS The Heat shock proteins (HSPs) were induced in filarial parasite S. cervi by incubated at 42 ◦C for 2 hrs. The 10% SDS PAGE of cytosolic extract showed several over-expressed bands. The MALDI LC/MS analysis of 29 kDa band showed 100% similarity with Bm14-3-3 like protein 2. Multiple sequence alignment of Bm14-3-3 like protein 2 sequence with W. bancrofti, Caenorhabditis elegans; Loa loa and Homo sapiens showed 100%, 86%, 83% and 78%, sequence similarity respectively. The antigenic efficacy of Sc14-3-3 protein was evaluated with different filarial sera using ELISA which showed cross reactivity in order to Endemic Normal(EN)
