Since exercise-induced oxidative stress has been shown to cause fluctuations in mucosal immunity (55, 56), it is feasible that an anthocyanin-mediated up-regulation of the secretory immune components (such as BD2 and IgA, observed over this 5 week period), may preserve this first line of innate defense to reduce the risk of opportunistic infection (57, 58). Here, CD79A is linked to Opportunistic infection.
