Lactate::fueling the fire starter

It is becoming increasingly appreciated that intermediates of metabolic pathways, besides their anabolic and catabolic functions, can act as signaling molecules and influence the outcome of immune responses. Although lactate was previously considered as a waste product of glucose metabolism, accumulating evidence has highlighted its pivotal role in regulating diverse biological processes, including immune cell polarization, differentiation and effector functions. In addition, lactate is a key player in modulating tumor immune surveillance. Hence, targeting lactate-induced signaling pathways is a promising tool to reduce inflammation, to prevent autoimmunity and to restore anti-tumor immune response.

Neonatal-Onset Multisystem Inflammatory Disease Responsive to Interleukin-1β Inhibition

Neonatal-onset multisystem inflammatory disease is characterized by fever, urticarial rash, aseptic meningitis, deforming arthropathy, hearing loss, and mental retardation. Many patients have mutations in the cold-induced autoinflammatory syndrome 1 (CIAS1) gene, encoding cryopyrin, a protein that regulates inflammation
