Tubastatin A prevented AD from increasing ed expression levels of TSLP, Toll-like receptor 4 (TLR4), Myeloid differentiation 88 (MyD88), and NF-κB (Figure 2C), inducing the binding of HDAC6 to MyD88 (Figure 2D, left) and the binding of FcεRI to Lyn (Figure 2D, left). Here, TSLP is linked to Alzheimer disease.
