Kinetics of cytokine profile in response to Mycobacterium bovis BCG and Streptococcus pyogenes activated cells.

ABSTRACT

The infection of epithelial cells is a necessary step for Mycobacterium bovis BCG dissemination, but the mechanism of mycobacterial epithelial interactions is not completely understood. Similarly, Streptococcus pyogenes is a strictly human pathogen that favorably colonizes the skin and the pharynx. Effective cytokine secretion is essential in order to fabricate a suitable inflammatory response against an infection. In this data article, the cytokine profile in BCG and S. pyogenes activated THP-1 cell line in media after the acute phase of infection by ELISA is described. The interleukin-8 level was increased in response to both BCG and S. pyogenes, but was quite prominent after 24 h and further increased upto 72 h post infection. On the other hand, an increase in IL-6 response to S. pyogenes was observed while there was no response to BCG even after 48 h of infection. A low level of TNF-α was detected upon BCG and S. pyogenes infection.
