Hyaluronic acid-conjugated lipid nanocarriers in advancing cancer therapy: A review.

Lipid nanoparticles are getting a lot of attention in cancer treatment because they're good at delivering drugs and reducing side effects. These things are like a flexible platform for getting anticancer meds where they need to go, especially when you add HA, a polymer that's known to target tumors. Hyaluronic acid is good because it homes in on tumor cells by latching onto CD44 receptors, which are often overproduced in cancer.

The molecular receptor NKBB enhances the persistence and anti-hepatocellular carcinoma activity of GPC3 CAR-T cells.

Chimeric antigen receptor (CAR) T cells have encouraging results in the treatment of hematological malignancies. However, CAR-T therapy still faces numerous challenges against solid tumors, such as hepatocellular carcinoma (HCC), owing to heterogeneous antigen expression in tumor cells, limited persistence of CAR-T cells, etc. Therefore, to treat HCC more effectively, we connected the molecular receptor NKBB to a second-generation glypican-3 (GPC3) CAR to construct GC3328z-NKBB CAR-T cells, which have double specific targets of GPC3 and NKG2DLs (natural killer group 2, member D ligands), dual co-stimulation of CD28 and 41BB, and a single CD3ζ chain.
