TNF and cerebral malaria: On account of the dependency of hyperinflammatory experimental cerebral malaria (eCM) on TNF, we performed patch-clamp studies in slices from eCM mice and showed that Plasmodium chabaudi infection augments Nav1.6 channel conductance of CA1 pyramidal neurons through the TNFR1–JAK2–FGF14–Nav1.6 signaling network, which leads to hyperexcitability.
