Human macrophage response to microbial supernatants from diabetic foot ulcers

Diabetic foot ulcers (DFUs) are a major clinical problem exacerbated by prolonged bacterial infection. Macrophages, the primary innate immune cells, are multifunctional cells that regulate diverse processes throughout multiple phases of wound healing. To better understand the influence of microbial species on macrophage behavior, we cultured primary human monocyte-derived macrophages from four donors for 24 hours in media conditioned by …
