MyD88 regulates TNF-α production by macrophages stimulated with B. pseudomallei. Bone marrow harvested from wild type or MyD88-/- mice was cultured in the presence of L929 cell conditioned media for 5–10 days to promote differentiation of macrophages before plating and stimulating with media alone or heat-killed BP-1 at a bacteria to cell ratio of 100. Supernatants were harvested after 24 hours and TNF-α production was measured by ELISA. Data plotted are means ± standard deviations of quadruplicate samples. § indicates p < 0.001 compared with wild type cells, using the t test. The data displayed represent one of two independently performed experiments.
