    Pharmacokinetics and Pharmacodynamics of Afamelanotide and its Clinical Use in Treating Dermatologic Disorders.
    Clin Pharmacokinet 2017 Jan 6. Epub 2017 Jan 6.
    Stadtspital Triemli, Institute of Laboratory Medicine, Zurich, Switzerland.
    Afamelanotide, the first α-melanocyte-stimulating hormone (MSH) analogue, synthesized in 1980, was broadly investigated in all aspects of pigmentation because its activity and stability were higher than the natural hormone. Afamelanotide binds to the melanocortin-1 receptor (MC1R), and MC1R signaling increases melanin synthesis, induces antioxidant activities, enhances DNA repair processes and modulates inflammation. The loss-of-function variants of the MC1R present in fair-skinned Caucasians are less effectively activated by the natural hormone. Read More

    The wide-ranging clinical implications of the short telomere syndromes.
    Intern Med J 2016 Apr;46(4):393-403
    Children's Medical Research Institute, The University of Sydney, Sydney, New South Wales, Australia.
    There is an increasing number of inherited disorders in which excessive telomere shortening underlies the molecular defect, with dyskeratosis congenita (DC) being the archetypal short telomere syndrome. DC is classically described as a mucocutaneous triad of oral leukoplakia, nail dystrophy and abnormal skin pigmentation. However, excessive telomere shortening can affect almost any organ system, so the clinical manifestations are protean, including developmental delay, cerebellar hypoplasia, exudative retinopathy, aplastic anaemia, acute myeloid leukaemia, idiopathic pulmonary fibrosis, idiopathic hepatic cirrhosis, head and neck cancer and dental abnormalities, and may be multi-systemic.
