Increased catalysis has been suggested to be an adaptive trait of enzymes to growth at lower temperature, but systematic analysis suggests that temperature exerts a weak selection pressure on enzyme rate enhancement, with observed variation arising from other evolutionary forces.

Aging is associated with mitochondrial and cytosolic iron accumulation in the brain, which is through increased local expression of hepcidin, and subsequent iron accumulation due to decreased iron export through ferroportin-1.

As well as preventing bone loss, bisphosphonate drugs may boost early immune responses in the lung by acting directly on alveolar macrophages that form one of the first lines of defence against infection.

Intrathecal injection of CSF1 induces greater upregulation of spinal microglial genes in male versus female mice, however, Treg depletion enhances microglial activation and restores pain hypersensitivity in the female mice.
A preclinical study using exogenous retinoids in a novel Usher syndrome 1F mouse model reveals a possible therapy to treat mutant PCDH15-mediated visual dysfunction.
