Impact of noncanonical NF-κB signaling during hapten-induced skin inflammation (C03)

• Subject Area: Immunology ; Dermatology
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 246807620

Our studies revealed that noncanonical NF-κB signaling is essential for adaptive immunity as mice deficient in NF-κB2 signaling were unable to develop progressive chronic contact hypersensitivity reactions. Thus, we aim to uncover how noncanonical NF-kB signaling modulates acute and chronic T cell driven inflammatory processes by (i) identifying the essential cellular players employing cell-type specific conditional NF-κB2-/- and NIKaly/aly mice in vivo, (ii) investigating cell specific impairments in activation, differentiation and survival in vitro, (iii) analyzing differences in T cell activation and leukocyte homing patterns in vivo and (iv) uncovering the efficacy of specific NF-κB2 inhibition in vitro and in vivo.
