Human urinary bladder transitional cell carcinomas acquire the functional Fas ligand during tumor progression

The interaction between FasL on tumor cells and Fas on lymphocytes may represent a tumor immune escape mechanism. We explored FasL expression and function in human urinary bladder transitional cell carcinomas (TCCs). FasL expression was observed in situ in 45% of TCCs (n = 45) and was absent in normal urothelium (n = 20). A correlation existed between FasL expression and high tumor grade (0% in G1,14% in G2, and 75% in G3; P < 0.0001) and stage (13% in superficial Ta-T1 versus 81% in invasive T2-T4; P < 0.0001). FasL function was shown by the ability of two FasL-positive primary culture TCC cell lines (established from two FasL-positive invasive TCCs) to induce Fas-mediated killing not only of conventional Fas-sensitive targets (such as Jurkat cells or phytohemagglutinin-lymphoblasts), but also of autologous T lymphocytes generated in a mixed lymphocyte tumor-cell culture. In addition, an association between FasL expression by TCC cells and activated caspase-8, -9, and -3 expression by interferon-gamma-producing CD8-positive tumor-infiltrating lymphocytes was observed in situ. Our results show a functional expression of TCC-expressed FasL that correlates with tumor progression. These results suggest that TCC-expressed FasL may induce apoptosis of anti-tumor T lymphocytes in vivo, providing new insights on the mechanisms involved in bladder TCC progression

AtopyReg®, the Prospective Italian Patient Registry for Moderate-to-Severe Atopic Dermatitis in Adults: Baseline Demographics, Disease Characteristics, Comorbidities, and Treatment History

background and objective atopyReg((R)) is a multicenter, prospective, observational, non-profit cohort study on moderate-tosevere atopic dermatitis in adults promoted in 2018 by the Italian society of dermatology and Venereology (SIDeMaST). we aimed to describe baseline demographics, disease characteristics, comorbidities, and therapeutic data of adult patients affected by moderate-to-severe atopic dermatitis.methods patients were selected based on the following inclusion criteria: age &gt;= 18 years; eczema area and severity Index score &gt;= 7 or a numeric rating scale sleep loss score = 7, or a dermatology life quality Index score &gt;= 10. score &gt;= 16 or localization in visible or sensitive areas (face, neck, hands, or genitalia), or a numeric rating scale itchDemographic and clinical data at baseline were recorded and analyzed. results a total of 1170 patients (male 51.1%; mean age: 44.7 years; range 18-90 years) were enrolled by 12 Italian dermatology units between January 2019 and november 2022. skin lesions were eczematous in 83.2% of patients, the most involved site were the flexures (53.9%), face (50.9%), and neck (48.0%). mean eczema area and severity Index score was 22.3, mean dermatology life quality Index value was 17.6, mean patient oriented Eczema measure score was 13.1, and mean numeric rating scale itch and sleep loss scores were 7.6 and 5.9, respectively. previous systemic therapies were corticosteroids in 77.7% of patients, antihistamines in 50.3% of patients, and cyclosporine A in 42.6% of patients.conclusions this baseline data analysis deriving from atopyReg((R)) provides real-life evidence on patients with moderate-to-severe atopic dermatitis in Italy confirming the high burden of atopic dermatitis with a significant impact on patients' quality of life
