Combination of Baricitinib and Phototherapy in Adults With Active Vitiligo: A Randomized Clinical Trial.

Importance: Vitiligo is a chronic autoimmune disorder leading to skin depigmentation and reduced quality of life (QOL). Patients with extensive and very active disease are the most difficult to treat.

Objective: To assess the efficacy and adverse events of baricitinib combined with narrowband UV-B in adults with severe, active, nonsegmental vitiligo.

Resident memory T cells in nonlesional skin and healed lesions of patients with chronic inflammatory diseases: Appearances can be deceptive.

Tissue-resident memory T (T) cells serve as a first line of defense in peripheral tissues to protect the organism against foreign pathogens. However, autoreactive T cells are increasingly implicated in autoimmunity, as evidenced in chronic autoimmune and inflammatory skin conditions. This highlights the need to characterize their phenotype and understand their role for the purpose of targeting them specifically without affecting local immunity.

The nucleolar protein GNL3 prevents resection of stalled replication forks.

Faithful DNA replication requires specific proteins that protect replication forks and so prevent the formation of DNA lesions that may damage the genome. Identification of new proteins involved in this process is essential to understand how DNA lesions accumulate in cancer cells and how they tolerate them. Here, we show that human GNL3/nucleostemin, a GTP-binding protein localized mostly in the nucleolus and highly expressed in cancer cells, prevents nuclease-dependent resection of nascent DNA in response to replication stress.

Evaluation of Facial Vitiligo Severity with a Mixed Clinical and Artificial Intelligence Approach.

Vitiligo is the most common depigmenting skin disorder. Given the ongoing development of new targeted therapies, it has become important to evaluate adequately the surface area involved. Assessment of vitiligo scores can be time consuming, with variations between investigators.
