It has been established that fibrinolytically active enzyme longolytine isolated from the culture fluid of the saprophyte fungus Arthrobotrys longa at intravenous injection favours the prolonged increase of the plasma fibrinolytic properties as well as activation of endogenic plasminogen. Maximum values of fibrinolytic activity have been marked in 5 and 30 min after enzyme intravenous injection. The plasminogen activity is high in 120 min. The fibrinolysis indexes--fibrinolytic activity of the euglobulin fraction and amount of plasminogen activator--in 3,5 and 5 times higher than in vitro at intravenous injection. The activation of coagulation system does not occur.

The effects of chronically stressing male mice can be transmitted across generations by stress-specific changes in their sperm miRNA content, which induce stress-specific phenotypes in their offspring. However, how each stress paradigm alters the levels of distinct sets of sperm miRNAs is not known. We showed previously that exposure of male mice to chronic social instability (CSI) stress results in elevated anxiety and reduced sociability specifically in their female offspring across multiple generations because it reduces miR-34c levels in sperm of stressed males and their unstressed male offspring.

Lipid nanoparticles (LNPs) are often liver tropic, presenting challenges for LNP-delivered mRNA therapeutics intended for other tissues, as off-target expression in the liver may increase side effects and modulate immune responses. To avoid off-target expression in the liver, miR-122 binding sites have been used by others in viral and non-viral therapeutics. Here, we use a luciferase reporter system to compare different copy numbers and insertion locations of miR-122 binding sequences to restrict liver expression.

Background: Human mesenchymal stromal cells (MSCs) possess regenerative potential due to pluripotency and paracrine functions. However, their stemness and immunomodulatory capabilities are sub-optimal in conventional two-dimensional (2D) culture.
Aim: To enhance the efficiency and therapeutic efficacy of MSCs, an -like 3D culture condition was applied.

Exemplified by successful use in COVID-19 vaccination, delivery of modified mRNA encapsulated in lipid nanoparticles provides a framework for treating various genetic and acquired disorders. However, lipid nanoparticles that can deliver mRNA into specific lung cell types have not yet been established. Here, we sought whether poly(®-amino ester)s (PBAE) or PEGylated PBAE (PBAE-PEG) in combination with 4A3-SC8/DOPE/cholesterol/DOTAP lipid nanoparticles (LNP) could deliver mRNA into different types of lung cells in vivo.

To investigate the potential mechanisms underlying neutrophil extracellular traps (NETs) confer ferroptosis resistance and CD8(+) T cell inhibition in lung adenocarcinoma (LUAD). By the intravenous injection of LLC cells into the tail vein, a LUAD mouse model was created. Phorbol-12-myristate-13-acetate (PMA) stimulated neutrophils to facilitate NETs formation and combined with NETs inhibitor DNase I to explore NETs mechanism on LLC cell proliferation, migration, ferroptosis resistance, and CD8(+) T cell activity.
