A little interpretation help for laypersons: the fact that stab1/clever-1 appears here or there does not mean that it is solely responsible for harmful immunosuppressive effects, nor does it mean that these effects can be removed with clever-1 targeting drugs.
This is an upstream/downstream or chicken/egg problem. Clever-1 appears “downstream” from where the problem lies.
If there’s a hole in a dam and a house 10km downstream is flooded, piling sandbags around the house won’t solve the actual problem.
