Loss of Tbk1 kinase activity protects mice from diet-induced metabolic dysfunction.

Objective: TANK Binding Kinase 1 (TBK1) has been implicated in the regulation of metabolism through studies with the drug amlexanox, an inhibitor of the IκB kinase (IKK)-related kinases. Amlexanox induced weight loss, reduced fatty liver and insulin resistance in high fat diet (HFD) fed mice and has now progressed into clinical testing for the treatment and prevention of obesity and type 2 diabetes. However, since amlexanox is a dual IKKε/TBK1 inhibitor, the specific metabolic contribution of TBK1 is not clear.

Impairment and recovery of hand use after unilateral section of the dorsal columns of the spinal cord in squirrel monkeys.

Damage to the ascending forelimb afferents in the dorsal columns (DCs) of the cervical spinal cord in monkeys impairs forelimb use, particularly hand dexterity. Although considerable recovery has been reported, interpretation of the results is complicated by the reproducibility of the lesion and behavioral assessment. Here, we examined the effects of a unilateral DC lesion at the C4-C6 spinal cord level in four adult squirrel monkeys.
