Histamine H3 receptors ligands act anorectic by blocking the H3 autoreceptors in the CNS, that results in increased synthesis and disinhibition of histamine release. Histamine further influencing H1 receptors participates in the leptin-dependent inhibition of food intake. It also affects

Pulmonary neuroendocrine (NE) cancer, including small cell lung cancer (SCLC), is a particularly aggressive malignancy. The lineage-specific transcription factors Achaete-scute homolog 1 (ASCL1), NEUROD1 and POU2F3 have been reported to identify the different subtypes of pulmonary NE cancers. Using a
