Stroma-derived Dickkopf-1 contributes to the suppression of NK cell cytotoxicity in breast cancer.
Nat Commun

Mechanisms related to tumor evasion from NK cell-mediated immune surveillance remain enigmatic. Dickkopf-1 (DKK1) is a Wnt/β-catenin inhibitor, whose levels correlate with breast cancer progression. We find DKK1 to be expressed by tumor cells and cancer-associated fibroblasts (CAFs) in patient samples and orthotopic breast tumors, and in bone.

During skin fibrosis, extracellular matrix (ECM) proteins are overproduced, and resident lipid-filled, mature dermal adipocytes are depleted in both human disease and mouse models. However, the mechanisms by which the reduction in lipid-filled adipocytes occurs during fibrosis are not well understood. Here, we identify that adipocyte lipolysis via the rate limiting enzyme, adipocyte triglyceride lipase (Atgl), is required for loss of adipose tissue during skin fibrosis in mice.

Chronic itch in older patients is a common problem, with a significant impact on quality of life. Chronic itch in the older population may be attributable to several causes, such as age-related changes, skin conditions, systemic conditions, medications, and psychological conditions. Given the complexity of itch in this population, comorbidities, and polypharmacy in most geriatric patients, treating chronic itch can be challenging for healthcare providers.

Article Synopsis
- Lichen nitidus (LN) is a rare skin condition that causes small, shiny, flat-topped bumps mainly in children and young adults, with its cause still unclear but likely linked to immune responses.
- The condition is typically asymptomatic and appears on areas like the trunk, upper limbs, and genitals, with diagnosis often based on a specific histological pattern.
- While LN usually resolves on its own, some cases may persist and require topical treatments, and this review provides insights into its clinical features and management strategies for dermatologists.
Recurrence of skin and soft tissue infections: identifying risk factors and treatment strategies.
Curr Opin Infect Dis
January 2025
Department of Medical and Surgical Sciences, Alma Mater Studiorum University of Bologna.
Purpose Of Review: Recurrent skin and soft tissue infections (RSSTIs) are challenging for the clinicians due to morbidity and healthcare-related costs. Here, we review updates on risk factors and management.
Recent Findings: RSSTIs rates range between 7 and 45%.
