Activation of the Drosophila innate immune system accelerates growth in cooperation with oncogenic Ras
Innate immune signaling acts as a surveillance system to fight potential infections, but it can become overactivated in malignant cells. These authors show that the tissue-protective functions of innate immune signaling involving oncogenic Ras can be misused by premalignant cells in Drosophila to induce overgrowth in the initial stages of tumor development.

Proteasome inhibition triggers tissue-specific immune responses against different pathogens in C. elegans
Protein quality control pathways play important roles in resistance against pathogen infection. This study shows that proteasome regulation keeps innate immune responses in check in a tissue-specific manner, against natural eukaryotic pathogens of the C. elegans epidermis and intestine.
How did our
#InnateImmune systems first evolve? Ed Culbertson & @tera_levin reveal origins of three families of
#antiviral proteins: CD-NTases (incl
#cGAS), STINGs &
#Viperins; each reveals a different story connecting animal & bacterial immunity

Eukaryotic CD-NTase, STING, and viperin proteins evolved via domain shuffling, horizontal transfer, and ancient inheritance from prokaryotes
How and when did our innate immune systems first evolve? This study analyses diverse eukaryotes, uncovering the evolutionary origins of three families of antiviral proteins: CD-NTases (including cGAS), STINGs and Viperins; each reveals a different story connecting animal and bacterial immunity.
The

Structural basis of G protein–Coupled receptor CMKLR1 activation and signaling induced by a chemerin-derived agonist
Chemokine-like receptor 1 (CMKLR1) responds to the adipokine chemerin and is highly expressed in innate immune cells. A high-resolution structure of CMKLR1 in complex with G protein and a peptide agonist, together with mutagenesis and computational simulations studies, reveals mechanisms of peptide agonist recognition, receptor activation, and G protein-coupling.
