Fine-tuning levels of filamins a and b as a specific mechanism sustaining Th2 lymphocyte functions.

Augmenting the portfolio of therapeutics for type 2-driven diseases is crucial to address unmet clinical needs and to design personalized treatment schemes. An attractive therapy for such diseases would consist in targeting the recruitment of T helper 2 (Th2) lymphocytes to inflammatory sites. Herein, we show the degradation of filamins (FLN) a and b by the ASB2α E3 ubiquitin ligase as a mechanism sustaining Th2 lymphocyte functions.
