[Cartesian Therapeutics] Cartesian Therapeutics announced that it has dosed the first patient in a Phase I/IIa multicenter clinical study evaluating Descartes-25, engineered to deliver a combination of synergistically active anti-myeloma therapies directly to tumor microenvironment, in patients with multiple myeloma.

[Annals of Neurology] Scientists investigated prospectively humoral and cellular responses to SARS-CoV-2 mRNA vaccination in 82 patients with neuroimmunologic disorders on anti-CD20 therapy and 82 age- and sex-matched healthy controls.

[Cell] In subjects ∼6 months post-vaccination, 90% and 87% of memory T cell responses were preserved against variants on average by AIM assay, and 84% and 85% preserved against Omicron.

[Nature Communications] Researchers showed that administration of the A2A receptor agonist CGS-21680 depleted established CD11c+T-bet+ B cells in ehrlichial-infected mice, in a B cell-intrinsic manner.

[Nature Communications] Investigators used multi-omics single-cell analysis to probe the dynamic immune responses in hospitalized patients with stable or progressive course of COVID-19, explore V(D)J repertoires, and assess the cellular effects of tocilizumab.
