| Research Abstract |
To study the roles of bacterial lipoproteins on bacterial invasion to host cells and on the effects on intracellular trafficking in host cells, attempts were made to purify a mycoplasmal lipoprotein, since some mycoplasmas are known to be able to invade into host cells. In this study, a lipoprotein was purified from M. hominis. The 40 kDa-lipoprotein was purified, and its N-terminal amino acid sequence was identical to that of P50 lipoprotein, which had already been reported as an adhesin of M. hominis. Interestingly, this lipoprotein could adhere to THP-1 cells but anti TLR2 antibody failed to inhibit adherence of this lipoprotein to THP-1 cells. We are now under preparation for submitting these results to an international journal on immunology.
