The effect of nematodes Dictyocaulus (D) filaria on phospholipid (PL) composition in the homogenate of sheep lungs has been demonstrated. The comparative analysis has shown no differences in the content and composition of PL in the lungs of healthy sheep and in nematodes. Infection of sheep by helminths was found to result in changes in the PL composition of sheep lungs. Thus, it is possible to conclude that D. filaria affecting structural and functional systems of the host causes changes in its PL content.

Background: Microglia, the innate immune cells of the brain, are a principal player in Alzheimer's Disease (AD) pathogenesis. Their surveillance of the brain leads to interaction with the protein aggregates that drive AD pathogenesis, most notably Amyloid Beta (Aβ). Aβ can elicit attempts from microglia to clear and degrade it using phagocytic machinery, spurring damaging neuroinflammation in the process.

A novel strain DW16-2, isolated from duckweed (), was taxonomically studied in detail. The analysis based on its 16S rRNA gene sequence revealed that the strain was most closely related to Y8 (98.8%), followed by YIM 61452 (98.

B0AT1 (SLC6A19) is a major sodium-coupled neutral amino acid transporter that relies on angiotensin converting enzyme 2 (ACE2) or collectrin for membrane trafficking. Despite its significant role in disorders associated with amino acid metabolism, there is a deficit of comprehensive structure-function understanding of B0AT1 in lipid environment. Herein, we have employed molecular dynamics (MD) simulations to explore the architectural characteristics of B0AT1 in two distinct environments: a simplified POPC bilayer and a complex lipid system replicating the native membrane composition.

Background: Sika deer (, 1838) antler is a highly esteemed tonic renowned for its abundant assortment of polypeptides, polysaccharides, amino acids, and minerals, and is recognized for its multifarious pharmacological properties. However, limited research has been conducted regarding the variation in composition of deer antlers between the upper and basal sections, as well as their pharmacological effects on immunological activity and anti-fatigue in mice. The objective of this study was to conduct a comprehensive analysis on the appearance, chemical composition, and pharmacological effects of different components within sika deer antlers.

Glioblastoma (GBM) is a malignant brain tumor with diffuse infiltration. Here, we demonstrate how GBM cells usurp guidance receptor Plexin-B2 for confined migration through restricted space. Using live-cell imaging to track GBM cells negotiating microchannels, we reveal endocytic vesicle accumulation at cell front and filamentous actin assembly at cell rear in a polarized manner.
