The mechanistic understanding of the complex between ALK kinase and its cytokine ligand ALKAL2 has been complicated by reports of diverse stoichiometries (2:1 vs 2:2). This study reanalyzes cryo-EM data originally interpreted as showing a 2:2 ALK-ALKAL2 complex, revealing that the dataset includes a population with a novel 2:1 stoichiometry.
Interesting contrast between the editor’s emphasis on Treg involvement in CD8 T cell priming and the complete absence of this point in the authors’ abstract.
Protein-based therapies have been developed to block cytokine signaling in a range of different diseases. These authors use a computational protein design approach to develop novel cytokine receptor antagonists and show that the designed proteins can inhibit G-CSFR activation in a cell model of acute myeloid leukemia.
#Age-dependent #Powassan virus #lethality is linked to glial cell activation & divergent neuroinflammatory #cytokine #responses in a murine model, J Virol.: https://journals.asm.org/doi/full/10.1128/jvi.00560-24?af=R
These findings correlate age-dependent #CNS cytokine responses & viral loads with POWV lethality & suggest potential neuroinflammatory therapeutic targets. Our results establish the age-dependent lethality of POWV in a murine #model that mirrors human POWV severity and long-term CNS pathology in the elderly.
