Receptor Occupancy Assays by Flow Cytometry: Benefits for Clinical Trials

XTalks

Generally, antibody-based therapeutics are one of the main types of drugs that are assessed using receptor occupancy assays as they bind to specific cell surface receptors through which they impact downstream intracellular signalling pathways. The antibodies are conjugated to fluorochromes for them to be detected.

CRISPR breakthroughs: New solutions for common diseases

Drug Discovery World

Incorporating in vivo pooled CRISPR screens has allowed for the interrogation of thousands of genetic perturbations in cells, leading to the determination of the involvement of molecules (PTPN2, ADAR1, or DHX37) in immune checkpoint inhibitor (ICI) responsiveness and T cell activation.

Flow cytometry technologies and cancer associated fibroblasts

Drug Discovery World

used conventional flow cytometry analysis and FACS (fluorescence-activated cell sorting) to validate a pan-CAF marker along with CAF subpopulation-specific markers identified using single-cell RNA sequencing 3. Fibroblasts in the tumour microenvironment. This is of particular importance in dense tissues like breast and pancreas. Elyada et al.
