Article Synopsis
  • - The management of hepatic adenoma in transgender individuals on hormone therapy is not clearly defined, particularly in relation to sex assigned at birth versus the therapy received.
  • - A case study is presented involving a transgender man who experienced hepatic adenomatosis with a molecular profile different from typical cases seen in cisgender males on testosterone.
  • - Discontinuing testosterone led to the self-resolution of the adenoma, suggesting the need for personalized treatment strategies in transgender patients, challenging the current norms based on biological sex.

Background: The hypothalamus is a crucial brain region that mediates the effects of insulin and leptin signals on peripheral metabolic functions. Previous research has shown that insulin signals in the hypothalamus act via multiple neuronal circuits and anabolic/catabolic pathways that converge on the vagus nerve and sympathetic fibers to coordinate energy metabolism in peripheral organs. Additionally, neuropeptide FF (NPFF) has been identified as a regulator of feeding behaviors and energy homeostasis in the hypothalamus, but the mechanisms underlying its involvement in metabolic control remain unclear.

The precise neural mechanisms underlying the pathogenesis of depression are largely unknown, though stress-induced brain inflammation and serotonergic plasticity are thought to be centrally involved. Moreover, we previously demonstrated that neuropeptide FF receptor 2 (NPFFR2) overexpression provokes depressive-like behaviors in mice. Here, we assess whether NPFFR2 is involved in priming of depressive-like behaviors and downregulation of serotonergic 1A receptor (5HT1AR) after lipopolysaccharide (LPS) treatment.

Background: Stimulation of trigeminovascular pathway is widely used to establish the headache animal model. Headache is a common neurological disorder, in which symptomatic attacks are mediated by calcitonin-gene-related peptide (CGRP). CGRP is synthesized and released from the trigeminal ganglion to transmit pain signals under stimulation.
