In vitro effects of three organic calcium channel blockers on the rat pineal gland [PDF]

open access: yes, 1992
The calcium signal has emerged as an imponant component of intracellular regulation. Pineal function was thought to be slowed by the prominent calcification seen with increasing age, but recently it has been shown that calcium plays a crucial role in the

Microglia-precursor cell interactions in health and in pathology [PDF]

open access: yes, 2018
Until recently, microglia were mainly known as the resident phagocytes of the brain, i.e. the ‘immunological warriors’ of the brain. However, extensive knowledge is being accumulated about the functions of microglia beyond immunity.

The pineal gland as a model to elucidate the primary mode of action of sympathoactive agents [PDF]

open access: yes, 1991
An attempt was made to use the pineal gland as a model for the study of the primary mode of action of sympathoactive agents. Two drugs were investigated, viz. alpha-methyldopa and ephedrine whose mode of action is not entirely clear.

The regulation of Serotonin N-acetyltransferase in the rat pineal gland [PDF]

open access: yes, 1993
The synthesis of the pineal hormone, melatonin, is finely regulated by the pineal enzyme serotonin N-acetyltransferase (NAT). In the absence of light, the activity of NAT is markedly enhanced by the release of nor-adrenaline from sympathetic nerve ...
