The target DNA specificity of the CRISPR-associated genome editor nuclease Cas9 is determined by complementarity to a 20-nucleotide segment in its guide RNA. However, can bind and cleave partially complementary off-target sequences, which raises safety concerns for use clinical applications. Here, we report crystallographic structures bound bona fide substrates, revealing that binding enabled range noncanonical base-pairing interactions within guide:off-target heteroduplex. Off-target...
The development of CRISPR genome editing has transformed biomedical research. Most applications reported thus far rely upon the Cas9 protein from Streptococcus pyogenes SF370 (SpyCas9). With many RNA guides, wildtype SpyCas9 can induce significant levels unintended mutations at near-cognate sites, necessitating substantial efforts toward strategies to minimize off-target activity. Although genome-editing potential thousands other orthologs remains largely untapped, it is not known how will...
Allogeneic chimeric antigen receptor (CAR) T cell therapies hold the potential to overcome many of challenges associated with patient-derived (autologous) CAR cells. Key considerations in development allogeneic include prevention graft-vs-host disease (GvHD) and suppression allograft rejection. Here, we describe preclinical data supporting ongoing first-in-human clinical study, CaMMouflage trial (NCT05722418), evaluating CB-011 patients relapsed/refractory multiple myeloma. is a...
The essential enzymatic cofactor NAD+ can be synthesized in many eukaryotes, including Saccharomyces cerevisiae and mammals, using tryptophan as a starting material. Metabolites along the pathway or on branches have important biological functions. For example, kynurenic acid act an NMDA antagonist, thereby functioning neuroprotectant wide range of pathological states. N-Formyl kynurenine formamidase (FKF) catalyzes second step biosynthetic by hydrolyzing N-formyl to produce formate. S. FKF...
Background aimsTherapeutic disruption of immune checkpoints has significantly advanced the armamentarium approaches for treating cancer. The prominent role programmed death-1 (PD-1)/programmed death ligand-1 axis downregulating T cell function offers a tractable strategy enhancing disease-modifying impact CAR-T therapy.MethodsTo address checkpoint interference, primary human cells were genome edited with next-generation CRISPR-based platform (Cas9 chRDNA) by knockout PDCD1 gene encoding PD-1...
