A bit like spiralling publication costs we need to start having a proper discussion around lab equipment servicing costs. These are often completely disproportionate to the cost of instrument and the service that is provided and seem to serve as a cash cow for vendors.

Nice paper, out today!
secure.jbs.elsevierhealth.com
MAIT cells exacerbate colonic inflammation in a genetically diverse murine model of spontaneous colitis
IL-17-producing lymphocytes are involved in both tissue repair and the propagation of inflammation, with their effects highly context-dependent. Mucosal-Associated-Invariant-T-cells (MAIT), a subset of innate-like T cells with features of both Th1 and Th17 lineages, are increasingly recognized for their roles in mucosal immunity. Here, we identified the Collaborative-Cross CC011/Unc strain, which spontaneously develops chronic colitis, as being enriched for MAIT cells. This expansion coincides with an age-related loss of intestinal barrier permeability and colonic inflammation.
