Study highlights differences in immune cell function between male and female mice
A new USC study of a common, yet poorly understood type of white blood cell reveals the human immune cell’s response to pathogens differs greatly by sex and by age. In this mouse study, males proved much more susceptible to a condition called sepsis than females. However, the scientists also found that the female disease-defense system is …
