Complement C1q was proved to be able to regulate the polarization of macrophages to the anti-inflammatory phenotype(M2 polarized),acting as an anti-inflammation molecule independent of the classical complement pathway.A high level of C1q expression has been detected in the tumor microenvironment(TME)of diverse tumors,including non-small cell lung cancer,in which C1q could be considered a predictor of poor prognosis.
