MAITabolism2 – the emerging understanding of MAIT cell metabolism and their role in metabolic disease

Mucosal associated invariant T (MAIT) cells are a population of unconventional innate T cells due to their non-MHC restriction and rapid effector responses. MAIT cells can recognise bacterial derived antigens presented on the MHC-like protein via their semi-restricted T cell receptor (TCR). Upon TCR triggering MAIT cells rapidly produce a range of effector molecules including cytokines, lytic granules and chemokines. This rapid and robust effector response makes MAIT cells critical in host responses against many bacterial pathogens. MAIT cells can also respond independent of their TCR via innate cytokines such as interleukin (IL)-18, triggering cytokine production, and are important in anti-viral responses. In addition to their protective role, MAIT cells have been implicated in numerous inflammatory diseases, including metabolic diseases often contributing to the pathogenesis via their robust cytokine production. Effector cells such as MAIT cells require significant amounts of energy to support their potent responses, and the type of nutrients available can dictate the functionality of the cell. Although data on MAIT cell metabolism is just emerging, several recent studies are starting to define the intrinsic metabolic requirements and regulators of MAIT cells. In this review we will outline our current understanding of MAIT cell metabolism, and outline their role in metabolic disease, and how disease-related changes in extrinsic metabolism can alter MAIT cell responses.

One of the most impressive T cell papers in the past decades. A truly humbling experiment and incredibly important insights into T cell biology. @Masopust_Vezys truly amazing. A must read for all T cell biologist (all immunologists really). nature.com/articles/s41586-022

T cells are capable of longevity and division at least 5x the normal organism lifespan (of mice). A 10 year mouse experiment ... slow 👏nature.com/articles/s41586-022

My highlights:
I) @DoctorKvoss & @JeffRathmell find T cell impairment in SLE arises from elevated Transferrin receptor & iron uptake @SciImmunology
II) GOT1 & CD8+ T cells @CellReports

Well, that clears that up then 😁.

Excellent explainer of what the “science is getting less disruptive” study DID and DIDN’T show.

Good man yourself Max 👍😁.

I'm the reporter who wrote the news story about the "science is getting less disruptive" @Nature paper.

I've seen some misconceptions floating around about what the paper did and did not show.

Heads up! Macrophages influence DC (and their own) metabolism through nitric oxide. A cautionary tale for GM-CSF-derived DC cultures!

More insight into how pressure from our immune system shapes the tumours that develop, from Ping-Chi Ho’s lab. @PCHo_Lab
Immunoediting empowers tumours to disarm T cell by imposing metabolic tug-of-war between tumor and infiltrating T cells thus forming the suppressive tumor microenvironment.

My highlights:

I) Microbial metabolite harmaline protects systemic inflammation via bile acid-GPR5 signalling
II) Sphingosine synthesis and S1P promote mito fission and trained immunity

Them bugs in our guts are sooo important. Must think more about how to support the good ones.

Microbial metabolite harmaline protects against virus-induced systemic inflammation.

"Because Big Pharma is unconvinced of the profit potential, they're abandoning gene therapies — not just for SCID but for scores of other rare diseases — even when they know the cures work. As a result, kids like Jakob will needlessly suffer and die, denied access to a permanent fix for their illnesses. What's keeping Jakob isolated from the rest of the world, unable to play with a dog or make a friend, isn't his disease. It's the marketplace."
