This case report describes a patient who developed multiple skin reactions, including eczematous lesions and alopecia areata, during adalimumab treatment, but found no improvement in pustulosis palmoplantaris with different biologics.

This study found that the catalytically inactive serine protease CAP1/Prss8 can still induce skin disorders in mice and is subject to inhibition by nexin-1, independent of its catalytic activity.

This study found that a phosphorus starvation-insensitive mutant of Arabidopsis thaliana shows altered root growth and auxin responses under low phosphate conditions compared to wild-type plants, suggesting a role for LPR1 in regulating these traits.

In this study, oral calcium pantothenate was associated with improvement in the inflammatory phase of discoid lupus erythematosus of the scalp, with the most marked response observed in subacute cases.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This study found that in biopsied skin samples of alopecia areata, a lower anagen/telogen ratio was associated with increased T cell infiltration, and enhancing the PD-1/PD-L1 axis may inhibit CD8+T cell infiltration and improve the condition.

This study suggests that cultured hair follicle dermal sheath cup cells exhibit immune privilege properties, partly through the expression of PD-L1, which impacts co-cultured immune cells' behavior.

This study found that PX-12 inhibited the NLRP3 inflammasome and reduced psoriasis-like symptoms in a mouse model, suggesting its potential as a treatment for psoriasis.

This study found that citrullinated proteins, which are implicated in rheumatoid arthritis, were abundant in outer membrane vesicles from Porphyromonas gingivalis but nearly absent in mutants, validating their approach to citrullinated peptide identification.

This study found that papillary dermal fibroblast progenitors in newborn mouse skin can be isolated and cultured to generate male germline cell precursors, demonstrating their potential through differentiation into cells with meiotic capability.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

In this study, the deletion of NIPP1 in keratinocytes led to chronic skin inflammation and epidermal changes in mice, with early cell-cycle arrest and premature senescence observed, potentially contributing to reduced mutagen sensitivity.

This study suggests that IL-1β may play a role in inflammatory signaling pathways in papulopustular rosacea, contributing to its pathogenesis.

This study reports that a new mouse model with a CARD14 mutation successfully mimics key human PRP symptoms, and anti-IL-17A antibody significantly reduces these symptoms.

This study found that palmoplantar pustulosis patients exhibited oral dysbiosis, particularly among those with pustulotic arthro-osteosis, as compared to healthy controls.

Brodalumab effectively treated a man's severe hand and foot psoriasis.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This study found that Ang1 improved survival and proliferation in human follicle dermal papilla cells under DHT-induced stress, suggesting potential as a therapeutic candidate for androgenetic alopecia.

This study found that a history of smoking significantly predicted a more refractory course of palmoplantar pustulosis, with associated comorbidities often including hypertension, type 2 diabetes mellitus, and thyroid diseases.

The researchers reported that disrupting the RPGRIP1L gene in mice impaired desmosome function, causing skin blistering, and their findings suggest that PKCβII inhibition could help treat pemphigus.

In a mouse model study, researchers observed that the absence of MCPIP1 in myeloid cells decreased susceptibility to chemically induced skin papillomas but caused significant hair loss and skin pigmentation changes, suggesting a role for MCPIP1 in skin carcinogenesis and follicle integrity.

This study suggests that compounds from turmeric and bitter have potential antiviral activity against the influenza A virus by inhibiting the polymerase PA-PB1, warranting further experimental verification.

This study found that Rap1 deficiency in mice may lead to telomere shortening, DNA damage, and impaired mitochondrial function, contributing to cardiac aging and dysfunction.

This study identified a new PNPLA1 mutation in a Spanish family with autosomal recessive congenital ichthyosis.

This study found that loss of Ptch1 function in mouse skin's basal cells is sufficient to rapidly induce tumors resembling human basal cell carcinoma, suggesting Ptch1 as a key tumor suppressor.

In this study, PINCH-1 gene loss in mouse epidermis led to detachment from the basement membrane, thickened skin, and hair loss, with findings suggesting PINCH-1 plays a role in keratinocyte adhesion through both ILK and EPLIN pathways.

In this study, researchers identified two novel peptidylarginine deiminases from treated rat keratinocytes, both showing enzyme activity with PAD‐R11 reflecting a characteristic of epidermal enzymes.

This study reported a rare case of pityriasis rubra pilaris-like skin reaction in an 18-year-old woman after starting ponatinib treatment for relapsed Philadelphia chromosome-positive acute lymphoblastic leukemia, which resolved after treatment adjustment and did not recur over 15 months.

This study found that PNU 157706 is a highly potent inhibitor of human 5α-reductase enzymes, showing a stronger and longer-lasting antiprostatic effect in rats compared to finasteride.

This study shows that NIPP1 deficiency in mouse epidermis leads to hyperproliferation, hair loss, and chronic skin inflammation, which can be partially alleviated by dexamethasone treatment.
