April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers found that the loss of SETDB1 in epidermal keratinocytes led to altered chromatin states, increased ERV expression, and activation of immune responses, while inhibiting these effects with certain antiviral drugs reduced skin inflammation and hair loss in a mouse model.
April 2023 in “Journal of Investigative Dermatology” This study reports distinctive clinical, trichoscopic, and histopathological features of fibrosing alopecia in a pattern distribution among Chinese patients, suggesting possible racial differences compared to previous studies primarily involving Caucasians.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study analyzed blood samples from individuals with alopecia areata and found that NKG2D+ immune cells, particularly memory-like NK cells, may better correlate with disease activity compared to CD8+ cells, though significant variability among individuals complicates these findings.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers found that Derinat treatment in mice maintained the hair cycle in the anagen phase and reduced TRPCs-mediated intracellular ROS accumulation, potentially improving hair growth by altering the skin microenvironment.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that treatment with ritlecitinib led to significant scalp hair regrowth in patients with alopecia areata at Weeks 24 and 48, with higher response rates observed in those receiving 50 mg compared to 30 mg doses.
April 2023 in “Journal of Investigative Dermatology” This study suggests that MPZL3, a mitochondrially localized protein, may play an integral role in regulating hair follicle cycles, with potential therapeutic implications for hair growth disorders if findings translate to humans.
April 2023 in “Journal of Investigative Dermatology” This study found that mRNA booster vaccinations for SARS-CoV-2 increased protective antibodies without worsening autoimmune disease activity in patients with pemphigus and bullous pemphigoid.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study revealed distinct cellular and transcriptomic differences among various subtypes of cutaneous T-cell lymphoma, particularly highlighting characteristics unique to folliculotropic mycosis fungoides.
April 2023 in “Journal of Investigative Dermatology” In this study, bariatric surgery in patients with morbid obesity improved various skin conditions, although acute telogen effluvium was common, with notable reductions in facial sebum and skin elasticity changes.
April 2023 in “Journal of Investigative Dermatology” This study found that adults with atopic dermatitis who were treated with baricitinib at doses of 2mg or 4mg experienced significant improvements in work productivity, potentially leading to substantial indirect cost savings for employers over 16 weeks.
April 2023 in “Journal of Investigative Dermatology” This study identified a new role for IL-4Ra-induced oxidative metabolism in wound macrophages, essential for balancing inflammatory response and promoting pro-fibrotic repair, suggesting a target for fibrosis prevention.
April 2023 in “Journal of Investigative Dermatology” This study found that treprostinil, a prostacyclin analog, significantly delayed fibroblast migration from healthy donors but did not affect fibroblast migration derived from diabetic foot ulcers.
April 2023 in “Journal of Investigative Dermatology” In this study, researchers found that the protein eIF4E is crucial for keratinocyte proliferation in psoriasis, suggesting it as a potential treatment target for the condition.
