V Prevot , B Dehouck , A Sharif , P Ciofi , P Giacobini , J Clasadonte

To read the full abstract: Endocr Rev 2018;39:3,333This review is interesting for several reasons. It focuses on a specific type of cells lining the wall of the third ventricle in the median eminence of the hypothalamus. This region acts both as a secretor of neuropeptides and as a sensor of the metabolic status of the periphery. These two functions imply a bidirectional physiological pathway: br...

To read the full abstract: Eur J Endocrinol. 2018 Apr;178(4):377-388[Comments on 7.7 and 7.8] Familial self-limited delayed puberty is highly heritable and has a clear genetic basis as described in the review written by Sasha Howard. Recent studies suggest that the genetic basis of self-limited delayed puberty is likely to be highly heteroge...
