**Researchers showed that CD8+ T cells trigger RIPK1-regulated endothelial death during cerebral malaria, and blocking this kinase prolongs mouse survival.**

CD8+ T cells trigger receptor-interacting serine/threonine-protein kinase 1 (RIPK1)–regulated death of brain endothelial cells during cerebral malaria, according to a study published in Science Advances [1]. Cerebral malaria is a severe complication of Plasmodium falciparum infection, causing blood-brain barrier disruption and fatal brain hemorrhage. The authors established that RIPK1 phosphorylation is also elevated in brain endothelial cells of human patients [1].

Using magnetic resonance imaging, 3D tissue-cleared brain imaging, endothelial translatomics, and cross-species pathology, the team identified a RIPK1-centered endothelial death program driven by cytotoxic T cells [1]. In vitro tests revealed that combining RIPK1 and caspase inhibitors protected cross-presenting endothelial cells from CD8+ T cell–mediated lysis [1].

In vivo experiments in mice demonstrated that brain endothelial-specific genetic inactivation of RIPK1 prolonged animal survival [1]. Systemic pharmacological inhibition of RIPK1 kinase activity yielded similar survival gains without altering blood parasitemia levels [1]. These results indicate that targeting RIPK1 protects vascular integrity independently of parasite clearance [1].
