To further validate the role of eosinophils in the asthma‐induced TMJOA alleviation, we depleted these cells using an anti‐IL‐5 antibody (TRFK5) and observed changes in the synovium, cartilage, and subchondral bone, while Sham rats received an irrelevant immunoglobulin G (IgG) control (Figure S3a, Supporting Information). Here, IL5 is linked to asthma.
