Cromolyn is a Food and Drug Administration–approved medication for treating allergic and inflammatory conditions such as asthma and MC disorders.37 With cromolyn treatment, synovial MC activation was reduced, leukocyte infiltration in injured labra was reduced, and both synovial and labral expression of IL-1β and MMP-13 were reduced after injury (Figure 11). This evidence concerns the gene IL1B and asthma.
