The use of CAR T-cell therapy has transformed outcomes for relapsed or refractory B-cell malignancies, but access to it remains extremely limited in some countries. Cartogene Therapeutics Pvt Ltd. aimed to address this need by in-licensing CGT-19, a CD19 CAR T construct from Vector Biomed Inc.
Previously, Chinese researchers used long-read RNA sequencing to identify a unique alternative splicing variant of CD44 transmembrane protein, named CD44E, which is highly expressed in hepatocellular carcinoma (HCC) tumors compared to adjacent nontumoral liver tissues. In a new study, the team analyzed the Genotype-Tissue Expression (GTEx) database and confirmed that CD44E expression is limited in essential normal organs, while CD44S standard isoform is broadly expressed on most cell types.
CAR T-cell therapy can be applied to treat some chronic infectious diseases, particularly to provide a functional cure for HIV-1 in people living with HIV. However, the effectiveness of CAR T cells for persistent suppression of HIV still faces many constraints, including the high mutation rate of reverse transcriptase, which enables the emergence of immune escape viral variants.
