The researchers next created uPAR-targeting CAR T cells, which they tested on naturally aged (18-to-20-month-old) mice. After injection with a single dose, the CAR T-cell-treated mice were ...

Has the CAR-T therapy been engineered to eliminate expression of the endogenous T-cell receptor ... Engraftment of CAR-T in tumor-bearing immunocompromised mice (e.g., NSG, NCG mice).

The Charles River models NCG-hIL2 and NCG-hIL15 are built on the NCG background, which lacks functional/mature T, B, and NK cells, and has reduced macrophage and dendritic cell function. NCG-hIL2 ...

Finally, to assess long-term toxicity, the researchers followed mice that received CARD11-PIK3R3 T cell therapies, including those that were part of the dose-response study, for up to 418 days.

Mice normally live about two years, and research found the uPAR-targeting CAR T cells persisted and expanded for more than 15 months in mice as they grew from youth into older age.

Regulatory T-cell therapy calms autoimmune response from gluten-sensitive T cells in mice By Darren Incorvaia Mar 20, 2025 7:16am ...

Amor Vegas' lab is now investigating whether CAR T cells let mice live not only healthier but also longer. If so, society will be one mouse step closer to the coveted fountain of youth.

An immunofluorescence image of an aged mouse liver. Expression of β-galactosidase (white) and uPAR (yellow) in senescent cells serve as target for engineered CAR T cells. Elimination of these ...

He hopes it will become possible to turn cells in the body directly into CAR T-cells without extracting them, which would greatly reduce costs. Journal reference: Nature Immunology DOI: 10.1038 ...

A CAR was initially developed with mouse IL-5 as the antigen-binding moiety. T-cells expressing this IL-5 CAR, which were eventually referred to as 5T cells, were found to effectively deplete IL-5 ...
