Caspase-1 autoproteolysis is differentially required for NLRP1b and NLRP3 inflammasome function
18 November 2014
In the context of the nucleotide-binding domain and leucine rich repeat pyrin containing 1b (NLRP1b) inflammasome activation by anthrax lethal toxin, we reveal a new role for full-length caspase-1. The work of Baptiste Guey in Dr Virginie Petrilli team directly demonstrates that the caspase-1 45-kDa zymogen is able to process pro–IL-1β and to induce pyroptosis, and that apoptosis-associated speck-like protein containing a CARD is dis- pensable for the activity of the NLRP1b inflammasome. This is in contrast to the NLRP3 inflammasome activity, which is inhibited in the absence of caspase-1 autoproteolyis. Our data, which highlight differential requirements for caspase-1 autoproteolysis in NLRP1b and NLRP3 inflammasome function, may have implications for pathogen recognition and response.
TGF-β prevents T follicular helper cell accumulation and B cell autoreactivity
27 August 2014
T follicular helper (Tfh) cells contribute to the establishment of humoral immunity by controlling the delivery of helper signals to activated B cells; however, Tfh development must be restrained, as aberrant accumulation of these cells is associated with positive selection of self-reactive germinal center B cells and autoimmunity in both humans and mice. The JC Marie labn from the Immunology Virology and inflammation dept of the CRCL, showed that TGF-β signaling in T cells prevented Tfh cell accumulation, self-reactive B cell activation, and autoantibody production. They demonstrated that TGF-β signaling is required for the thymic maturation of CD44+CD122+Ly49+CD8+ regulatory T cells (Tregs), which induce Tfh apoptosis and thus regulate this cell population. Moreover, peripheral Tfh cells escaping TGF-β control were resistant to apoptosis, exhibited high levels of the antiapoptotic protein BCL2, and remained refractory to regulation by CD8+ Tregs. The unrestrained accumulation of Tfh cells in the absence of TGF-β was dependent on T cell receptor engagement and required B cells.Together, these data indicate that TGF-β signaling restrains Tfh cell accumulation and B cell–associated autoimmunity and thereby controls self-tolerance. This work has been published in Journal of Clinical Investigation.
