Exploring the molecular mechanisms by which secretory phospholipase a2 regulates lymphatic endothelial cell dysfunction by activating macrophages.

This study offers new insights into the dual role of secretory phospholipase A2 (sPLA2) in lymphedema, highlighting its impact on lymphatic endothelial cell (LEC) functionality. Through transcriptomic analyses and co-culture experiments, we observed that sPLA2 has both protective and detrimental effects on human LECs (HLECs), mediated by macrophage activation. Our findings reveal that while low levels of sPLA2 promote LEC health, excessive sPLA2 leads to dysfunction, emphasizing the significance of the sPLA2/PLA2R axis and arachidonic acid metabolism (AA) in lymphedema pathology.

In recent years, combining nanozymes with hydrogels to jointly promote wound healing has attracted increasing research interest.

Immunological function of Bombyx Toll9-2 in the silkworm (Bombyx mori) larval midgut: Activation by Escherichia coli/lipopolysaccharide and regulation of growth.

Toll receptors are important regulators of insects' innate immune system which, upon binding of pathogen molecules, activate a conserved signal transduction cascade known as the Toll pathway. RNA interference (RNAi) is a powerful tool to study the function of genes via reverse genetics. However, due to the reported refractory of RNAi efficiency in lepidopteran insects, successful reports of silencing of Toll receptors in the silkworm Bombyx mori have not been reported yet.

BmPGPR-L4 is a negative regulator of the humoral immune response in the silkworm Bombyx mori.

Toll, immune deficiency and prophenoloxidase cascade represent vital immune signaling pathways in insects. Peptidoglycan recognition proteins (PGRPs) are innate immune receptors that activate and regulate the immune signaling pathways. Previously, we reported that BmPGPR-L4 was induced in the silkworm Bombyx mori larvae by bacteria and peptidoglycan challenges.

Epigenetic regulations of cellular senescence in osteoporosis.

Osteoporosis (OP) is a prevalent age-related disease that is characterized by a decrease in bone mineral density (BMD) and systemic bone microarchitectural disorders. With age, senescent cells accumulate and exhibit the senescence-associated secretory phenotype (SASP) in bone tissue, leading to the imbalance of bone homeostasis, osteopenia, changes in trabecular bone structure, and increased bone fragility. Cellular senescence in the bone microenvironment involves osteoblasts, osteoclasts, and bone marrow mesenchymal stem cells (BMSCs), whose effects on bone homeostasis are regulated by epigenetics.
