Health is a unity and harmony within the mind, body and spirit which is unique to each person, and is as defined by that person. The level of wellness or health is, in part, determined by the ability to deal with and defend against stress. Health is determined by physiological, psychological, socio-cultural, spiritual, and developmental stage variables.
The ins and outs of how neutrophils combat microbes
Immunity :: The ins and outs of how neutrophils combat microbes
Immune cells known as neutrophils produce reactive oxygen intermediates (ROIs) to combat infection with microbes that can cause diseases such as pneumonia. New insight into the molecular pathway regulating neutrophil production of ROIs in mice has been provided by Wojciech Swat and colleagues at Washington University School of Medicine, St. Louis.They were found to be part of a signaling pathway that linked integrin-mediated adhesion to the NADPH oxidase complex that produces ROIs. Importantly, mice lacking Vav were unable to control infection with either Pseudomonas aeruginosa or Staphylococcus aureus, 2 common microbes associated with fatal cases of hospital-acquired pneumonia.
