Cytokines released by THP-1 cells after infection with mycoplasma strains.

<p>Supernatants from THP-1 cells infected with mycoplasma strains (MOI 1∶10) were collected and IL-1β and TNF-α concentrations were determined using an ELISA kit from eBioscience. <b>A.</b> Release of IL-1β by THP-1 cells and <b>B.</b> Release of TNF-α by THP-1 cells. PBS, phosphate buffered saline control; G37 and MS5 are wild type <i>msrA</i> mutant <i>M. genitalium</i> strains respectively; HKG37 represents heat killed wild type <i>M. genitalium</i>. * = p≤0.05 vs wild type G37.
