IL6 and cancer: In an insightful work, considering that inflammation promotes cancer growth and suppresses immune responses against the cancer cells, peptides modified with anti-inflammatory moieties were used to obtain hydrogel carriers in the design of cancer vaccines; the incorporation of OVA in the hydrogel by vortexing hydrogel and OVA increased IgG and IgG2a production besides stimulating the secretion of IFN-γ and IL-6 cytokines in accordance with an enhanced dual immune responses of the humoral and cellular types [152].
