Summary: This review presents the innovative concept of sebaceous immunobiology, discussing the physiological and pathophysiological tasks of sebaceous glands, the role of sebaceous lipids in the skin barrier function and innate immune processes, the connection between sebaceous glands and hair follicle morphogenesis, the involvement of inflammation in acne, the behavior of sebocytes as immune regulators, the regulation of sebaceous gland function by immune cells, the contribution of sebaceous glands to the immune response of perifollicular infiltrate, the role of inflammatory mediators and pattern recognition receptors in acne pathogenesis.

Summary: Research has shown a decline in the stem cell ability of CD133-positive stem/progenitor cells in the salivary glands of aged mice, with a decrease in the number of these cells and a lower sphere formation capacity compared to young and adult mice. CD133-positive cells in aged mice exhibited lower gene expression of aging-related genes than those in young and adult mice, indicating a potential role of FoxO3a in inhibiting stem cell aging via oxidative stress.

Summary: Although sebocytes from sebaceous glands and preputial glands share common lipid-producing properties, significant differences were found in the expression levels of enzymes involved in the biogenesis of specialized lipid classes. This suggests major developmental, functional, and biosynthetic differences between the two gland types.

Summary: We present a case of sebaceous lymphadenoma, a rare benign salivary gland neoplasm, in a 74-year-old female. The preoperative diagnosis of sebaceous neoplasms can be challenging. This manuscript provides detailed information about the epidemiological characteristics, histogenesis, and cytomorphologic differential diagnosis of sebaceous salivary gland neoplasms, with a focus on sebaceous lymphadenoma.

Summary: Sebaceous neoplasms are a group of tumors with sebaceous differentiation commonly found in the face and neck. Most of these tumors are benign, but malignant ones are rare. They are strongly associated with the Muir-Torre Syndrome. Patients suspected to have this syndrome should undergo neoplasm excision, followed by histopathologic and additional immunohistochemistry and genetics examinations.

Summary: This study reveals that breast cancer in BRCA1 mutation carriers may originate from luminal cells and abnormal luminal progenitor cells in normal tissues may contribute to the development of basal-like tumors. Additionally, ERhigh luminal breast cancer may stem from mature luminal cells.

Summary: The literature review suggests that low-dose isotretinoin can safely and effectively treat acne in patients on renal dialysis, improving their quality of life. Although limited, more studies could help further establish the safety of isotretinoin in these patients.

Summary: Analysing surgically removed caruncular tumors over the past 22 years reveals a wide spectrum of mostly benign tumors, with oncocytomas and malignant lesions mainly occurring in patients over 60 years old. Clinical diagnosis was confirmed in only 68.3% cases, highlighting the importance of detailed histopathological examination for accurate diagnosis and management of potentially malignant caruncular lesions.

Summary: By analyzing 15,000 young and aged HSC transcriptomes, the study identified 15 groups of HSCs showing rare and new specific abilities that change with age. This established a new reference map of HSC differentiation and revealed a potential mechanism that delays differentiation in aged HSCs, potentially contributing to age-related hematologic diseases.

Summary: Our findings show that the literature is categorized according to the treatment modalities ranging from conventional techniques such as oral isotretinoin and cryotherapy to more advanced topical PDT, lasers and a combination of both. We found that effectiveness does not depend on the technique itself but instead on the number of lesions, financial cost, psychological factors, skin phototype and age. Our work shows that SGH can be treated effectively by customizing the treatment modality according to different parameters, while effectively maintaining clearance of SGH lesions with best cosmetic outcome.

Summary: This study reveals the significant role of Sox9 in mediating autophagy-dependent vSMC phenotypic modulation and the development of TA. Inhibition of Sox9 expression can attenuate neointimal formation, providing a potential therapeutic approach for vascular pathologies.

Summary: In this study, it was found that near-infrared radiation causes sebaceous gland enlargement and skin thickening in hamsters. The mechanism involves the proliferation of sebocytes and the increase in reactive oxygen species levels, leading to the transcriptional augmentation of epidermal growth factor receptor production. These findings provide new evidence for the understanding of the effects of near-infrared radiation on the skin.
