AI Article Synopsis

  • The suspension from the thymuses of TL(+) mice mainly contains TL(+) cells, but also has some TL(-) cells.
  • The TL(-) cells show a higher reactivity in graft versus host scenarios compared to the entire population of cells, meaning they require fewer cells to cause a reaction.
  • The TL(-) thymocytes may represent an early stage in the process where TL(+) thymocytes mature into fully functional immune cells.

Article Abstract

Suspensions prepared from thymuses of TL(+) mice contain a majority of TL(+) cells and a minority of TL(-) cells. The graft versus host reactivity of the TL(-) population is much greater than that of the whole population, as judged by the numbers of cells required to give splenic enlargements in Simonsen's assay. It is proposed that the TL(-) thymocyte represents a stage in the differentiation of TL(+) thymocytes into immunocompetent lymphocytes.

Pancreatic ductal adenocarcinoma (PDAC) driven by the mutation presents a formidable health challenge because of limited treatment options. MRTX1133 is a highly selective and first-in-class KRAS-G12D inhibitor under clinical development. Here, we report that the advanced glycosylation end product-specific receptor (AGER) plays a key role in mediating MRTX1133 resistance in PDAC cells.

Oncolytic adenoviral therapy is a promising approach for pancreatic cancer treatment. However, the limited capacity of murine cells to produce infectious viral progeny precludes the full evaluation of the virotherapy in a suitable immunocompetent mouse model. Here, we report that the murine KPC-I cell line, established from pancreatic tumors developed in ; ; mice, is susceptible to adenoviral replication and generates a progeny of infective virions similar to those from infected human A549 cells.

Paradoxical control of multifocal mammary oncogenesis by radiation therapy.

Oncoimmunology

December 2025

Cancer Signaling and Microenvironment Program, Fox Chase Cancer Center, Philadelphia, PA, USA.

In an immunocompetent mouse model of multifocal, metachronous HR mammary carcinogenesis, we have recently demonstrated that a superior control of primary neoplastic lesions by focal radiotherapy does not necessarily translate into improved oncosuppression at non-irradiated (pre)malignant tissues. These data point to a link between local tumor control by radiotherapy and systemic oncogenesis that remains to be fully understood.

Background: Targeting glutamine metabolism has emerged as a promising strategy in cancer therapy. However, several barriers, such as anti-tumor efficacy, drug toxicity, and safety, remain to be overcome to achieve clinical utility. Prior preclinical studies had generated encouraging data showing promises of cancer metabolism targeting drugs, although most were performed on immune-deficient murine models.

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal forms of cancer, and despite low incidence rates, it remains the sixth leading cause of cancer related deaths worldwide. Immunotherapy, which aims to enhance the immune system's ability to recognize and eliminate cancer cells, has emerged as a promising approach in the battle against PDAC. PARP7, a mono-ADP-ribosyltransferase, is a negative regulator of the type I interferon (IFN-I) pathway and has been reported to reduce anti-tumour immunity.
