‘Man flu’ may be ruled by sex hormones

PERHAPS women should be more sympathetic when ‘man flu’ presents?

A study from the University of Queensland suggests men are more susceptible than women to rhinoviruses which cause symptoms of the common cold.

Researchers assessed the immune response of mononuclear cells to rhinovirus in 63 healthy volunteers.

They found that men made a much weaker immune response to rhinoviruses than women, as measured by levels of cytokines in their mononuclear cells.

Levels of INF-γ were 3.5 times lower in men than women, and IL-13 levels were twice as low in men as in women.
