The effectiveness of CAR T therapy has been observed in mouse models of different solid neoplasms, including ovarian carcinomas and mesotheliomas, in which the chimeric receptors recognised human MSLN and the inflammatory cytokines secreted by the T cells (including IL-2, IL-6, tumour necrosis factor alpha, and interferon-y) produced cytotoxic effects in the cancer cells (Figure 3B) (Table 2) [90,91]. Here, IL6 is linked to ovarian carcinoma.
