This study reported that shallot extract showed strong antimicrobial activity, and supplementation with shallot powder may enhance broiler chicken growth, immune response, and microbiome balance.

Secukinumab reduces immune activity in hidradenitis suppurativa skin.

This study found that the immune-competent B6. Cg‐Tyr c−2J Hr hr /J congenic mouse line had a more pronounced delayed sunburn response and different proliferative skin reactions to UV exposure compared to SKH 1 mice.

This study evaluated interleukin-26's antimicrobial activity in Hidradenitis Suppurativa and explored its potential role in chronic skin inflammation.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study reviews the regulatory mechanisms and molecular processes governing stem cell activity in hair follicles, highlighting their roles in hair regeneration and potential implications for treating hair and skin disorders.

This review discusses the potential immuno-regenerative effects of polydioxanone threads in hair loss treatment, focusing on tissue responses and immune modulation, but does not report clinical results.

Ritlecitinib reduces alopecia areata symptoms by blocking JAK3/TEC signaling and T-cell activity.

This study developed a mathematical model to explore the interactions between hair cycle dynamics and immune system activity in alopecia areata, providing insights into disease progression and potential targets for treatment by simulating immune response effects on hair follicles.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This study reports on a zinc-coordinated tri-enzyme nanogel system (Zn@nGSC) that mimics natural enzymatic processes to enhance enzymatic activity and cascade efficiency, showing potential in wound healing, hyperglycemia treatment, and antibacterial effects in a murine model of post-pancreatectomy.

This review highlights that T cells are crucial in regulating hair follicle regeneration and their disruption can lead to alopecia, providing insights into hair disorders related to T cell immune balance and hair follicle regeneration.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

This study found that miR-486 and miR-451 levels were reduced in alopecia areata-affected skin, and delivering their mimics to mice mitigated symptoms by reducing inflammation and immune activity.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

This study found that EP 2 signaling is crucial for macrophage recruitment and inflammatory regulation in the injured heart, impacting cardiac repair processes.

This study investigated chitosan–hydroxyapatite biocomposites, finding them to enhance anti-inflammatory cytokine expression, support cellular activities, and reduce pro-inflammatory cytokines in a dermatitis model, while highlighting gaps in understanding their immune modulation and issues with reproducibility for clinical use.

This study found that Euph E and Euri A showed strong anti-inflammatory activity and modulated cytokine and immune functions in macrophages, related to specific signaling pathways.

In this study, Luan et al. showed that epidermal stem cells play a key role in wound healing by coordinating the recruitment of regulatory T cells and neutrophils, which help balance immune tolerance and inflammation.

This study found that alopecia areata is associated with distinct systemic and tissue immune signatures, with macrophages implicated as contributors to hair loss, suggesting potential therapeutic targeting of macrophage activity.

In this study, researchers reported that the Pinkie mutation in mice, affecting RXRa activity, leads to skewed Th1 development and suggests RXRa's role in Th2 differentiation, impacting immune responses.

In this clinical study, melatonin treatment reduced oxidative stress markers and enhanced hair growth in patients with alopecia areata, potentially through its effects on the immune system and antioxidant activity.

This study found that theabrownin-selenium nanoparticles (TB-Se NPs) effectively target Malassezia-induced dermatitis through a dual antifungal and immunomodulatory mechanism, suppressing fungal overgrowth, reducing inflammation, and enhancing immune memory to prevent recurrence in a dermatitis model.

This study observed distinct sex differences in hair growth cycles and regeneration in C3H/He mice, noting that females regenerated hair faster after adhesive material application, whereas males were more reliant on macrophage activity for this process.

This study observed that in human scalp hair follicles, BTNL2 expression is lower in stressed conditions, which correlates with increased cytotoxic activity by gamma/delta and CD8+ T cells, suggesting a possible role for BTNL2 in controlling immune responses relevant to alopecia areata.

This study found that a single instance of acute skin stretching can enhance immune surveillance and improve vaccine delivery by increasing skin permeability and promoting immune cell recruitment without causing tissue damage.

This study found that Hashimoto's thyroiditis and alopecia areata show distinct gut microbial patterns, with specific microbes like Bacteroides fragilis and Microbacterium sp. T32 potentially linked to autoimmune activity.

This study reported that mannan oligosaccharides improved the fur quality, immune response, antioxidant status, and gut microbiota of fur-growing raccoon dogs, suggesting they could potentially replace antibiotics in their diet.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.
