Did you mean Autoimmune Mechanisms?

Glossary Autoimmune Mechanisms

body's immune system mistakenly attacks its own tissues

Autoimmune mechanisms refer to the processes by which the body's immune system mistakenly attacks its own tissues, thinking they are foreign invaders. This can lead to various autoimmune diseases, such as alopecia areata, where the immune system targets hair follicles, resulting in hair loss. Understanding these mechanisms is crucial for developing treatments that can modulate the immune response and prevent tissue damage.

research 3D organotypic skin models recapitulate autoantibody-driven pemphigus pathomechanisms and targeted therapeutic response

1 citations , January 2026 in “Science Advances”

This study developed a 3D bioprinted skin model to mimic pemphigus vulgaris, providing a tool to study disease mechanisms and test targeted therapies by reproducing the architecture and pathogenic disruptions of native skin.

research Linear immunoglobulin A/immunoglobulin G bullous dermatosis associated with Vogt-Koyanagi-Harada disease

11 citations , May 2011 in “The Journal of Dermatology”

This case report describes a possible association between Vogt-Koyanagi-Harada disease and linear IgA/IgG bullous dermatosis in a 35-year-old Japanese male, though coincidence cannot be ruled out.

research Depressive Disorder and Dermatological Autoimmune Diseases

1 citations , May 2024 in “Journal of Clinical Medicine”

This study found a reciprocal correlation between depressive disorders and several dermatological autoimmune diseases, such as psoriasis and lupus, suggesting that inflammation may be a shared pathomechanism for these conditions.

research The pharmacological treatment of alopecia areata

July 2023 in “University of Debrecen Electronic Archive (University of Debrecen)”

This review suggests that novel treatment developments targeting the pathomechanics of alopecia areata, such as JAK inhibitors, show promise, although optimal treatment strategies are still under investigation.

research The role of janus kinases in the treatment of autoimmune skin diseases

1 citations , February 2021 in “Farmacja Polska”

This article reviews the role of the JAK-STAT pathway in inflammatory skin diseases and considers the therapeutic benefits of JAK inhibitors, presenting them as promising treatments but reports no new experimental results.

learn Cetirizine

Could cetirizine help control autoimmune triggers in alopecia areata? No published trial has tested cetirizine in alopecia areata; one registered trial has not reported results. Small trials in pattern hair loss report modest benefit, so any use for alopecia areata is off-label and unproven.

learn Tofacitinib

What is tofacitinib, and why is it discussed in relation to autoimmune-related hair loss such as alopecia areata? Tofacitinib is a prescription JAK inhibitor approved for rheumatoid arthritis, psoriatic arthritis and ulcerative colitis — not for alopecia areata. It is discussed for hair loss because a 2014 case report and a 2016 open-label trial reported regrowth in severe alopecia areata, but that use is off-label, the regrowth relapsed after stopping, and the drug carries an FDA boxed warning.
