Atopic dermatitis (AD) is a prevalent dermatologic condition affecting both children and adults, and the debate surrounding its association as either a risk or protective factor for malignancies has garnered significant attention. Proposed mechanisms suggest that AD may act protectively against cancer formation through chronic immune system activation or create an inflammatory state conducive to cancer development. This review discusses the relationship between AD and various skin cancers, solid tumors, and hematologic malignancies.

Although tumor-intrinsic fatty acid β-oxidation (FAO) is implicated in multiple aspects of tumorigenesis and progression, the impact of this metabolic pathway on cancer cell susceptibility to immunotherapy remains unknown. Here, we report that cytotoxicity of killer T cells induces activation of FAO and upregulation of carnitine palmitoyltransferase 1A (CPT1A), the rate-limiting enzyme of FAO in cancer cells. The repression of CPT1A activity or expression renders cancer cells more susceptible to destruction by cytotoxic T lymphocytes.

The poor efficacy of chimeric antigen receptor T-cell therapy (CAR T) for solid tumors is due to insufficient CAR T cell tumor infiltration, in vivo expansion, persistence, and effector function, as well as exhaustion, intrinsic target antigen heterogeneity or antigen loss of target cancer cells, and immunosuppressive tumor microenvironment (TME). Here we describe a broadly applicable nongenetic approach that simultaneously addresses the multiple challenges of CAR T as a therapy for solid tumors. The approach reprograms CAR T cells by exposing them to stressed target cancer cells which have been exposed to the cell stress inducer disulfiram (DSF) and copper (Cu)(DSF/Cu) plus ionizing irradiation (IR).

Here we describe a broadly applicable nongenetic approach that simultaneously addresses the multiple challenges of CAR T as a therapy for solid tumors. The approach massively reprograms CAR T cells by exposing them to stressed target cancer cells which have been exposed to the cell stress inducer disulfiram (DSF) and copper (Cu)(DSF/Cu) plus ionizing irradiation (IR).

Article Synopsis
  • - Chondrosarcoma is a type of bone cancer that usually resists chemotherapy and radiation, posing challenges for treatment, especially in advanced cases.
  • - CSPG4 is a protein often found in various cancers, including chondrosarcoma, making it a potential target for antibody therapies; specifically, CSPG4 targeted CAR T cell therapy has been successful in other cancers.
  • - In this study, CSPG4 was present in 71% of conventional chondrosarcoma tumors but only 15% of dedifferentiated ones, and CSPG4 CAR T cells effectively destroyed over 80% of CSPG4-positive chondrosarcoma cells, indicating a promising treatment avenue.

Background: Sorafenib, a kinase inhibitor, is a standard treatment for advanced hepatocellular carcinoma (HCC) but provides only a limited survival benefit. Disulfiram (DSF), a drug for treating alcoholism and a chelator of copper (Cu), forms a complex with Cu (DSF/Cu). DSF/Cu is a potent inducer of autophagic apoptosis of cancer stem cells, which can demonstrate drug resistance.

Theme groups at thirty.

Int J Group Psychother

October 2009

This article is a 30-year retrospective of the emergence of the theme group movement in college counseling centers and in psychotherapy in general. It describes the evolution of interventions in this modality, defines and describes their unique features and approaches, and illustrates, via comparison of two theme groups on grief, the maturation and incorporation of more evidence-based and apt formats and dynamics over that period of development.

We describe antimicrobial resistance among Escherichia coli isolated from free-living Canada Geese in Georgia and North Carolina (USA). Resistance patterns are compared to those reported by the National Antimicrobial Resistance Monitoring System. Canada Geese may be vectors of antimicrobial resistance and resistance genes in agricultural environments.
