nanoCAR-T mRNA service

Non-viral chimeric antigen receptor (CAR)-T cells are gaining attention for their cancer-killing ability with reduced side effects. Traditional CAR-T cell engineering relies on lentivirus, which causes random chromosomal integration, permanent CAR expression, and adverse effects from persistent immunologic stimulation. To address these issues, mRNA-based CAR-T therapy offers a promising alternative by enabling temporary yet effective CAR expression in T cells.

We provides a nanoCAR-T mRNA service that advances CAR-T cell therapy by integrating its NanoAb™ VHH antibody platform, mRNA IVT technology, and lipid nanoparticle (LNP) delivery. This approach allows precise ex vivo delivery of CAR instructions to T cells via mRNA encapsulated in ionizable lipid nanoparticles. Unlike conventional CAR-T therapies that use single-chain variable fragments (scFv) from monoclonal antibodies, We incorporates smaller VHH antibodies for high affinity antigen targeting. This allows access to cryptic antigen epitopes often missed by traditional antibodies and improve tissue penetration into the highly complex tumor microenvironment. The smaller VHH antibodies also enable the construction of bispecific CAR-T to expand its cancer-killing options.
