英文摘要
ABSTRACT
Membraneless compartments play a vital role in maintaining cellular and organismal homeostasis by
modulating cell survival and cell death. Stress granules, and inflammasome-induced specks are
membraneless compartments that provide contrasting cell fate choices to the cells – survival or pyroptosis
(programmed cell death) during physiological or virus induced cellular stress. NLRP3, a global sensor of
pathogen–associated molecular patterns (PAMPs) and danger–associated molecular patterns (DAMPs),
senses cellular perturbations in the cytosol to trigger the assembly of a large caspase-1-activating protein
complex termed the NLRP3 inflammasome. Autoproteolytic maturation of caspase-1 due to NLRP3
inflammasome activation leads to pyroptosis, and maturation of pro-inflammatory cytokines interleukin (IL)-
1β and IL-18. Despite the ability of NLRP3 to respond to diverse cues of cellular or virus induced stress,
mechanisms controlling the cross-talk between inflammasomes and stress granules remain elusive. In our
quest to study this cross-talk, we have identified DDX3X, a stress granule component, as an upstream
regulator of NLRP3 inflammasome to canonical and viral triggers. In this R01 renewal, we propose to identify
the molecular and cellular mechanisms of DDX3X-mediated NLPR3 inflammasome activation and its
modulation by stress signals during inflammation and viral infections. Understanding the cross-talk between
cellular stress response molecules and innate immune signaling will lead to novel therapeutic targets for
inflammatory and infectious diseases.
