Emerging role of Tissue Resident Memory T cells in vitiligo: From pathogenesis to therapeutics.

Autoimmun Rev 2021 Jun 10;20(8):102868. Epub 2021 Jun 10.

C. G. Bhakta Institute of Biotechnology, Uka Tarsadia University, Tarsadi, Surat 394350, Gujarat, India. Electronic address:

Vitiligo is an acquired depigmenting disorder which affects both skin and mucous membranes and autoimmunity has been strongly suggested to play a role in loss of melanocytes. The recurrence of skin macules at the same sites where they were observed prior to the treatment, suggests the existence of Tissue Resident Memory T cells (TRMs) that persist within the skin or peripheral tissues with a longer survivability. Emerging studies have shown that reactivation of these skin TRMs results into autoreactive TRM cells in various autoimmune diseases including vitiligo. Read More

Dermatology, Maharashtra Medical Foundation, Joshi Hospital, Pune, India.

Vitiligo is a common depigmenting condition that carries a high psychosocial morbidity, especially when it occurs over exposed areas like lips. Many of the current topical and systemic therapies are less effective in lip vitiligo, and surgical modality remains the mainstay of treatment of lip vitiligo. The 308-nm excimer laser in combination with topical calcineurin inhibitors and calcipotriene is effective in the treatment of lip vitiligo. Read More

Vitiligo and chronic autoimmune thyroiditis.

J Med Life 2021 Mar-Apr;14(2):127-130

Department of Endocrinology, Clinical County Hospital, Cluj-Napoca, Romania.

Vitiligo, the discoloration of the skin, has different autoimmune mechanisms reflected by many biomarkers as shown by skin histology, staining for CD4 and CD8 T lymphocytes, chemokine ligand 9 or circulating cytokines such as interleukin (IL)-1 beta, interferon (IFN)-gamma, transforming growth factor (TGF)-beta, antibodies, markers of oxidative stress, chemokines, and others. In this narrative review, we aim to overview vitiligo in relationship with chronic autoimmune thyroiditis. Regarding vitiligo, more than 50 different genetic loci have been associated with this disease, and the heritability is high. Read More

RIP1-mediated necroptosis facilitates oxidative stress-induced melanocyte death offering insight into vitiligo.

J Invest Dermatol 2021 Jun 5. Epub 2021 Jun 5.

Department of Dermatology, Xijing hospital, Fourth Military Medical University, Xi'an, Shannxi, China. Electronic address:

Vitiligo is a common depigmentation disease characterized by the melanocyte death which is attributed to various mechanisms such as apoptosis and autoimmune destruction. However, whether necroptosis, a newly discovered way of cell death, plays a key role in the pathogenesis of vitiligo is still elusive has not been well studied. In this study, we found that necroptosis markers including phosphorylated receptor-interacting protein 3 (p-RIP3) and phosphorylated mixed lineage kinase domain-like protein (p-MLKL) were positive in melanocytes from vitiligo perilesional skins, which supported the existence of necroptosis in vitiligo.

Janus Kinase Inhibitors in Dermatology: Part 1 - General Considerations and Applications in Vitiligo and Alopecia Areata.

Actas Dermosifiliogr 2021 Jun 19;112(6):503-515. Epub 2021 Mar 19.

Servicio de Dermatología, Hospital de la Santa Creu i Sant Pau, Universitat Autònoma de Barcelona, Barcelona, Spain.

Dermatologists' interest in the Janus-associated kinase/signal transducers and activators of transcription (JAK/STAT) pathway has been growing as evidence builds to support its key role in the pathogenesis of inflammatory skin diseases. Because certain proinflammatory cytokines use the JAK/STAT pathway for signal transduction, it has become a promising therapeutic target in diseases where selective modulation of the immune system can be useful. We aim to review current knowledge of the JAK/STAT signaling pathway and its role in immune-mediated skin diseases. Read More

Exp Dermatol 2021 Jun 3. Epub 2021 Jun 3.

Department of Dermatology, University of Münster, Münster, Germany.

The SARS-CoV-2 pandemic has evolved to a global health problem with a dramatic morbidity and mortality rate impacting our daily life and those of many patients. While there is evidence that some diseases are associated with an increased risk for development of a more severe course of COVID-19, little is known on protective conditions. Importantly, clearance of viral infection and protection against disease manifestation crucially depends on functional innate and adaptive immunity and the interferon signalling axis. Read More
