This study identified peripheral myeloid cells as the earliest dysregulated immune cells in PINK1 KO mice with Parkinson’s-like symptoms following intestinal infections, suggesting that PINK1 regulates gut immune functions linked to early Parkinson’s disease mechanisms.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This study highlights that biological therapy, which stimulates the immune system through various methods like cytokine injections and immune checkpoint inhibition, shows promise for treating melanoma based on laboratory and clinical studies.

This review explored the relationship between autoimmune thyroiditis and various autoimmune skin conditions, highlighting shared genetic markers and immunological mechanisms, such as disrupted immune tolerance and oxidative stress, which may contribute to the development of these disorders.

This review discusses the use of umbilical cord blood in regenerative medicine, focusing on collection, banking processes, and ethical considerations, without presenting new clinical results.

This study concluded that the Wnt signaling pathway does not significantly influence human keratoacanthoma development, but the overexpression of Sox9 suggests alternate signaling involvement.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

This review summarizes existing knowledge of how the WNT signaling pathway affects mesenchymal stem cells under various conditions, highlighting challenges and mechanisms for clinical applications.

This review discusses factors affecting hair aging, such as inflammation and UV exposure, and examines potential anti-aging benefits of antioxidants and nutraceuticals for hair, but reports no new clinical results.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

In this study, overexpression of YAP1 was found to promote adipogenic differentiation of goat adipose-derived mesenchymal stem cells by up-regulating LATS2 expression and activating the Hippo pathway's negative feedback loop.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This article reviews the complexity and diverse manifestations of systemic lupus erythematosus, highlighting potential genetic, hormonal, and environmental factors in its pathogenesis without presenting new clinical findings.
