Photo‐Responsive Decellularized Small Intestine Submucosa Hydrogels

Advanced Functional Materials, Volume 34, Issue 36, September 4, 2024.
This work demonstrates an aqueous synthesis of norbornene‐modified decellularized small intestine submucosa (dSIS‐NB) and its photocrosslinking into bioactive hydrogels. Compared with uncrosslinked dSIS and collagen matrices, orthogonally crosslinked dSIS‐NB hydrogels support rapid dissemination of cancer cells and have superior vasculogenic and ...

Proteasome composition in immune cells implies special immune‐cell‐specific immunoproteasome function

European Journal of Immunology, Volume 54, Issue 4, April 2024.
Immune cells from human peripheral blood and immune cells from murine spleen have been analyzed for their proteasome composition. All analyzed immune populations express almost solely immunoproteasome subunits and rather small proportions of standard proteasome subunits.

Single‐cell RNA sequencing reveals inflammatory retinal microglia in experimental autoimmune uveitis

MedComm, Volume 5, Issue 4, April 2024.
Inflammatory retinal microglia with high expression of Cd74 and Ccl5 are identified at the disease peak of experimental autoimmune uveitis (EAU) by single‐cell RNA sequencing. Targeting Cd74 and Ccl5 effectively alleviated microglial activation and disease phenotype in the EAU model .

High methane concentrations in tidal salt marsh soils: Where does the methane go?

Global Change Biology, Volume 30, Issue 1, January 2024.
Salt marsh soils can contain high concentrations of methane, but what happens to this gas? There are a few possibilities, including vertical and lateral transport, storage within the soil, and/or oxidation resulting in transport as carbon dioxide or dissolved inorganic carbon.
