This special issue of the Journal of Molecular Histology is devoted to the unique phenomena of migration and adult neurogenesis observed in the olfactory system. Neural progenitors migrate from the olfactory placode and epithelium (OE) into the central nervous system (CNS) and from the forebrain ventricular region to the olfactory bulb (OB). Not unexpectedly, there are a number of controversies with regard to the mechanisms regulating these phenomena in both developing and adult animals. One especially controversial issue common to both the peripheral (OE) and central (OB) systems is the identity of the slowly dividing multipotent stem cell and the mechanisms regulating the lineage specification of these progenitors which eventually differentiate into neurons and glia. Nine contributions from leading laboratories address these and other issues with respect to progenitors and their integration into OE and OB circuitry in several species.

Periodontal diseases afflict 20-50% of the global population and carry serious health and economic burdens. Chronic periodontitis is characterized by inflammation of the periodontal pocket caused by dysbiosis. This dysbiosis is coupled with an increase in the population of Treponema denticola, a spirochete bacterium with high mobility and invasivity mediated by a number of virulence factors.

Feeding behavior is regulated by a complex network of endogenous neuropeptides. In chordates, this role is suggested to be under the control of diverse factors including thyrotropin-releasing hormone (TRH). However, whether this regulatory activity of TRH is functionally conserved in non-chordate metazoans, and to what extent this process is underpinned by interactions of TRH with other neuropeptides such as cholecystokinin (CCK, known as a satiety signal), remain unclear.

Increasing evidence implicates disruptions in testicular fatty acid metabolism as a contributing factor in non-obstructive azoospermia (NOA), a severe form of male infertility. However, the precise mechanisms linking fatty acid metabolism to NOA pathogenesis have not yet been fully elucidated. Multi-omics analyses, including microarray analysis, single-cell RNA sequencing (scRNA-seq), and metabolomics, were utilized to investigate disruptions in fatty acid metabolism associated with NOA using data from public databases.

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.
