  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In female mice lacking the leptin receptor in GABAergic neurons, intracerebroventricular kisspeptin‑10 elicited robust gonadotropin responses.

    In plain wordsIn female mice lacking leptin receptors in certain nerve cells, kisspeptin‑10 given into the brain caused strong gonadotropin release.

    Summary
    Intracerebroventricular administration of kisspeptin-10 to Vgat-Cre;Lepr(lox/lox) female mice elicited robust gonadotropin responses, suggesting normal gonadotropin-releasing hormone neuronal and gonadotrope function.

    Summary · context
    To address this gap, we explored the contribution of predominantly inhibitory (GABAergic) neurons versus excitatory (glutamatergic) neurons in the female mouse by selective ablation of the leptin receptor in each neuronal population: Vgat-Cre;Lepr(lox/lox) and Vglut2-Cre;Lepr(lox/lox) mice, respectively.

    In ovariectomized female mice lacking the leptin receptor in GABAergic neurons, Kiss1 mRNA in the arcuate nucleus was significantly lower than in control animals.

    In plain wordsIn these mice, the body's own kisspeptin gene activity in the arcuate nucleus was lower than in control mice.

    Summary
    However, adult ovariectomized Vgat-Cre;Lepr(lox/lox) mice displayed significantly reduced levels of Kiss1 (but not Tac2) mRNA in the arcuate nucleus, and a reduced compensatory luteinizing hormone increase compared with control animals.

    Summary
    These animals also exhibited a compromised positive feedback response to sex steroids, as shown by significantly lower Kiss1 mRNA levels in the AVPV, compared with Lepr(lox/lox) mice.
