p16ink4a Positivity of Melanocytes in Non-Segmental Vitiligo

Researchers found that p16ink4a immunoreactivity was not restricted to melanocytes but also existed in fibroblasts; the number of p16ink4a-positive fibroblasts was significantly increased in lesional skin compared to perilesional skin and normal controls.

Multiple Signaling Pathways Converge on Proapoptotic Protein BAD to Promote Survival of Melanocytes

The authors showed that melanocyte survival was mediated by diverse, nonredundant signaling pathways, including ERK1/2, AKT, PKA, and PKC.

CD49a Regulates Cutaneous Resident Memory CD8+ T Cell Persistence and Response

Investigators demonstrated that CD8+ tissue-resident memory cell expressing the α1 chain (CD49a) was expressed early following T cell activation in vivo, and TGF-β and IL-12 induced CD49a expression by CD8+ T cells in vitro.

Intracellular Virus Sensor MDA5 Exacerbates Vitiligo by Inducing the Secretion of Chemokines in Keratinocytes under Virus Invasion

Researchers clarified that virus invasion significantly activated MDA5 and further potentiated the keratinocyte-derived CXCL10 and CXCL16 which are the two vital chemokines for the cutaneous infiltration of CD8+ T cells in vitiligo.
