NOVEL CHIMERIC ANTIGEN RECEPTOR AND USE THEREOF

Provided is a chimeric antigen receptor, comprising an antigen binding region, a transmembrane domain and an intracellular signaling region. The antigen binding region comprises an antibody specifically targeting CD7, and the intracellular signaling region consists of a co-stimulatory domain, a primary signal transduction domain, and a ?C chain or intracellular region thereof. Also provided are an engineered immune cell comprising the chimeric antigen receptor and a pharmaceutical composition thereof, and use of the engineered immune cell/pharmaceutical composition for treating cancers.

GENETICALLY-MODIFIED IMMUNE CELLS COMPRISING A MICRORNA-ADAPTED SHRNA (SHRNAMIR)

The present invention encompasses genetically-modified immune cells (and populations thereof) expressing a microRNA-adapted shRNA (shRNAmiR) that reduces the expression of a target endogenous protein. Methods for reducing the expression of an endogenous protein in an immune cell are also provided wherein the method comprises introducing a shRNAmiR that targets the endogenous protein. Using shRNAmiRs for knocking down the expression of a target protein allows for stable knockdown of expression of endogenous proteins in immune cells.

NOTCH RECEPTORS WITH HINGE DOMAIN
20240075062 · 2024-03-07 ·

The present disclosure generally relates to, inter alia, a new class of receptors engineered to modulate transcriptional regulation in a ligand-dependent manner. Particularly, the new receptors, even though derived from Notch, do not require the Notch negative regulatory regions previously believed to be essential for the functioning of the receptors. In addition, the new receptors described herein incorporate an extracellular oligomerization domain to promote oligomer formation of the chimeric receptors. The disclosure also provides compositions and methods useful for producing such receptors, nucleic acids encoding same, host cells genetically modified with the nucleic acids, as well as methods for modulating an activity of a cell and/or for the treatment of various health conditions such as cancers.
