The ultrastructure of epididymal basal cells in adult castrated and castrate-androgen supplemented rhesus monkey was studied. Due to reduction in the height of the epithelium, three months after castration their number appeared to have increased. In the initial segment dark basal cells occupied more area in the epithelium and their cytoplasm showed the presence of large vacuoles. Cells that resembled dark basal cell were found at all heights of the epithelium. In all the segments, dark basal cells developed pseudopod-like structures. Pale basal cell cytoplasm was filled with lipofuscin pigment granules. Androgen replacement therapy for 30 days prior to autopsy at 90 days did not bring about any significant changes in the ultrastructure of both the types of basal cell. However, the size of the dark basal cell appeared to have decreased. The possible role of basal cells in the disposal of products accumulated in the principal cells under normal and altered endocrine conditions in discussed.

Fatty acid and retinol binding proteins (FARs) are lipid-binding protein that may be associated with modulating nematode pathogenicity to their hosts. However, the functional mechanism of FARs remains elusive. We attempt to study the function of a certain FAR that may be important in the development of Nippostrongylus brasiliensis.

Background: Acute lung injury (ALI) is a disordered pulmonary disease characterized by acute respiratory insufficiency with tachypnea, cyanosis refractory to oxygen and diffuse alveolar infiltrates. Despite increased research into ALI, current clinical treatments lack effectiveness. Tetramethylpyrazine (TMP) has shown potential in ALI treatment, and understanding its effects on the pulmonary microenvironment and its underlying mechanisms is imperative.

Human nasal epithelium (HNE) organoid models of SARS-CoV-2 infection were adopted globally during the COVID-19 pandemic once it was recognized that the Vero cell line commonly used by virologists did not recapitulate human infection. However, the widespread use of HNE organoid infection models was hindered by the high cost of media and consumables, and the inherent limitation of basal cells as a scalable continuous source of cells. The human Calu-3 cell line, generated from a lung adenocarcinoma, was shown to largely recapitulate infection of the human epithelium and to preserve the SARS-CoV-2 genomic fidelity.

Glioblastoma (GBM) infiltrates the brain and can be synaptically innervated by neurons, which drives tumor progression. Synaptic inputs onto GBM cells identified so far are largely short-range and glutamatergic. The extent of GBM integration into the brain-wide neuronal circuitry remains unclear.
