There are actually two studies showing no role of the adaptive immune system in complex tissue regeneration in salamanders and zebrafish.

Very curious study on tissue regeneration. It’s not clear yet whether it is applicable to humans, but it provides definitive results for salamander biology.

Why are there so many peptide–MHC/HLA prediction tools? It seems like anyone who can develop one is doing so and making bold claims, yet most lack independent validation. What’s the value?

You're right that #covid isn't like other flus/colds. You're wrong that covid isn't still killing people left & right anymore. It still is #killing people left & right, as well as #disabling a large amount of people who become infected more than once. The problem is governments aren't providing the public with any accurate reports, have stopped funding proper tracking methodology of both infections & covid related deaths, have misled public & conned people into cognitive dissonance/normalizing #eugenics #publichealth policies.

I work in #healthcare. I'm in multiple hospitals, long term care homes, private assisted living homes & multiple medical clinics for my contract work. People are still dying from covid & other illnesses that are triggered/re-triggered from covid infections. Governments are still lying to everyone about it all - while countless people with covid, #longcovid plus those with zero covid & at high risk due to compromised #immunology are dehumanized/devalued by government & treated like crap by ignorant general public.

Normalizing/ignoring covid will only lead to multiple #medical #crisis points & will end up collapsing already overstrained public health care systems. No stable economy either, when more people are becoming #disabled from long covid & unable to work/be limited with work.

It’s too simplistic to eliminate one immune cell type and attribute muscle effects directly to it, especially since such changes can significantly alter the microbiota, which may actually drive the observed outcome.

Washington University researchers have discovered that mRNA cancer vaccines activate anti-tumor immune responses through an unconventional pathway utilizing two distinct subsets of dendritic cells. This challenges the previous assumption that only one specific immune cell subtype was required for these vaccines to effectively target and destroy tumors.
