Zusammenfassung der Projektergebnisse

The transcription factor (TF) IRF4 belongs to the family of interferon regulatory factors (IRF) consisting of nine members in mice and humans which play important roles in the regulation of innate and adaptive immune responses as well as in oncogenesis. IRF4 has long been known to be essential for the differentiation of the effector CD4+ T cell-subsets Th2, Th9, Th17 and Tfh, however its role for the differentiation of CD8+ T cells has not been closely evaluated until 2013. During the funding period, our group has demonstrated a crucial role of IRF4 for the development of the cytotoxic T lymphocytes (CTL)s and for “low” cytotoxic CD8+ T cell subpopulations including Tc9 and Tc17 cells. Furthermore, we have delineated the supportive function of low cytotoxic Tc9 and Tc17 cells for CD4+ T cell activity in allergic airway disease and autoimmunity of the central nervous system, respectively.
