Targeting RGMb interactions: Discovery and preclinical characterization of potent anti-RGMb antibodies blocking multiple ligand bindings.

Therapeutic efficacy with durable responses has been demonstrated with several antibody drugs that block key immune checkpoint receptors, including PD-1, PD-L1, and CTLA-4. Despite the success of these drugs, a substantial proportion of patients do not benefit. Targeting multiple inhibitory pathways simultaneously to augment anti-tumor immunity has proven to be a promising approach.

ΔFosB is part of a homeostatic mechanism that protects the epileptic brain from further deterioration.

Activity induced transcription factor ΔFosB plays a key role in different CNS disorders including epilepsy, Alzheimer's disease, and addiction. Recent findings suggest that ΔFosB drives cognitive deficits in epilepsy and together with the emergence of small molecule inhibitors of ΔFosB activity makes it an interesting therapeutic target. However, whether ΔFosB contributes to pathophysiology or provides protection in drug-resistant epilepsy is still unclear.
