Resumen:
Neutrophils have the shortest lifespan among leukocytes and usually die via apoptosis. We previously reported that low pH, a hallmark of inflammatory processes and solid tumors, moderately delays neutrophil apoptosis. Here we analyzed whether fever-range hyperthermia (39.5°C) was able to modulate the anti-apoptotic effect induced by low pH (pH 6.0). Hyperthermia markedly increased neutrophil survival induced by low pH (anexinV/PI staining/flow cytometry): % apoptosis = 72±5, 45±6, 70±7, and 19±3, for neutrophils cultured for 18 h at pH 7.3/37ºC, pH 6.0/37°C, pH 7.3/39.5ºC, and pH 6.0/39.5°C, respectively (p
