Abstract
BACKGROUND Hair loss is a common dermatological condition including various types such as alopecia areata, androgenetic alopecia, etc. Minoxidil is a topical medication used for treating hair loss, which is effective for various types of alopecia. However, minoxidil has limitations in treating hair loss, such as slow onset of action and low efficacy, and it cannot effectively inhibit one of the major pathogenic factors of hair loss - excessive oxidative stress. METHODS Transition metal elements with rapid electron transfer, such as molybdenum, have been extensively studied and applied for inhibiting oxidative stress. We established a mouse model for hair growth and intervened with nano-sized molybdenum, minoxidil, and a combination of both. The physicochemical properties of nano-sized molybdenum enabled it to mediate oxidative stress more quickly. RESULTS The results showed that nano-sized molybdenum can accelerate hair growth, increase the number of local hair follicles, and reduce the expression of oxidative stress-related molecules such as iNOS, COX2, and androgen receptors. The combination of nano-sized molybdenum and minoxidil showed an additive effect in promoting hair growth. CONCLUSION Our findings suggest that nano-sized molybdenum might be a potential topical medication for treating hair loss by inhibiting the oxidative stress pathway. Nano-sized molybdenum, alone or in combination with minoxidil, could be a promising therapeutic approach for patients with hair loss, particularly those who do not respond well to current treatments. Further clinical studies are warranted to confirm the efficacy and safety of this novel treatment.

Xu Q, Xu N. JAK Inhibitors as Potential Therapeutic Strategy for the Dilemma of Psoriasis Concurrent with Dermatomyositis in the SARS-CoV-2 Era. Clin Cosmet Investig Dermatol 2023; 16:1059-1062. [PMID: 37102163 PMCID: PMC10124744 DOI: 10.2147/ccid.s403970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 04/15/2023] [Indexed: 04/28/2023]
Abstract
Dermatomyositis is a rare inflammatory disease with potentially life-threatening systemic involvement that is treated with systemic corticosteroids. However, when psoriasis coexists with dermatomyositis, the administration of corticosteroids may exacerbate psoriasis after withdrawal, posing a treatment dilemma. Our search of the literature revealed 14 cases where various treatments were used, including methotrexate, corticosteroids, cyclosporin, ustekinumab, mycophenolate mofetil, and azathioprine. While methotrexate showed promise, it carries risks, and corticosteroids were used despite their potential to exacerbate psoriasis. Based on transcriptomic data analysis of psoriasis and dermatomyositis, the type II interferon-mediated signaling pathway was enriched in both diseases. Medication targeting this pathway, such as JAK inhibitors, could be a potential solution for the psoriasis concurrent with dermatomyositis dilemma, as JAK inhibitors have been proven effective in treating both dermatomyositis and psoriasis, with some being FDA-approved for treating COVID-19. Therefore, JAK inhibitors may be a potential therapeutic strategy for psoriasis concurrent with dermatomyositis in the SARS-CoV-2 era.

Abstract
Androgenic alopecia affects men and women today, where many factors can be the unknown cause of it. It is essential to find a good, effective, and inexpensive treatment for it, as it is a prevalent dermatological condition. Many drugs like minoxidil (MXD) and finasteride (FNS) are commercially used for its treatment but we are still lacking in terms of a complete cure for alopecia. In this study, we came up with different treatment options for alopecia and assessed their advantages and disadvantages. Not only is the treatment part is essential, but the mode of drug delivery is equally important when it comes to hair and its growth for the maximum output. The following discussion considers the idea of nanoparticles (NPs) loaded with drugs and biomaterials used for the treatment of alopecia.

Abstract
Androgenetic alopecia (AGA), the most prevalent type of hair loss in clinic, is induced partly by insufficient perifollicular vascularization. Here we designed a dissolvable microneedles (MNs) patch that was loaded with conditioned media (CM) derived from hypoxia-pretreated mesenchymal stem cells, which contained elevated HIF-1α. The CM-integrated MNs patch (designated as CM-MNs) can puncture the stratum corneum and deliver the pro-angiogenic factors directly into skin in a one-step and minimally invasive manner. Meanwhile, the administration of CM-MNs induced a certain mechanical stimulation on the skin, which can also promote neovascularization. With the combined effects of the pro-angiogenic factors in CM and the mechanical stimulation induced by MNs, CM-MNs successfully boosted perifollicular vascularization, and activated hair follicle stem cells, thereby inducing notably faster hair regeneration at a lower administration frequency on AGA mouse model compared with minoxidil. Furthermore, we proved that the inhibition of perifollicular angiogenesis restrained the awakening of hair follicle stem cells, elucidating the tight correlation between perifollicular angiogenesis and the activation of hair follicle stem cells. The innovative integration of CM and MNs holds great promise for clinical AGA treatment and indicates that boosting angiogenesis around hair follicles is an effective strategy against AGA.
