IL10 and congenital rubella syndrome: In addition to already described virulence strategies for S. aureus, our group has recently suggested two novel ones: (i) An immunomodulatory effect, modulated via induction of excessively high levels of IL-10, an anti-inflammatory cytokine (Chau et al., 2009; Schwartz et al., 2017), and (ii) a deleterious effect on in-vitro models of epithelial regeneration and wound repair, particularly in cell cultures raised form CRS patients (Valera et al., in press).
