Melittin, a natural bioactive peptide derived from bee venom, has been reported to exert anticancer and immunomodulatory effects; however, the cellular targets and molecular mechanisms underlying its selective action on TAMs remain incompletely defined. This study aimed to investigate the immunomodulatory effects of melittin on TAM subsets and to identify the molecular determinant responsible for its selectivity toward M2-like macrophages. Macrophage subsets were analyzed following melittin treatment using flow cytometry, gene expression analysis, and immunofluorescence. Binding interactions were assessed by biochemical and biophysical approaches. Tumor growth and immune cell composition were examined in wild-type and CD18-deficient mice. Melittin treatment selectively reduced M2-like TAM populations while increasing infiltration of CD8<sup>+</sup> cytotoxic T cells in tumor tissues. Mechanistic analyses revealed that melittin preferentially binds to the integrin subunit CD18 (ITGB2), which is enriched in M2-polarized macrophages, leading to disruption of M2-associated phenotypes in vitro. Notably, genetic deletion of CD18 abolished the M2-suppressive and antitumor effects of melittin in vivo. These findings demonstrate that CD18 is functionally required for the immunomodulatory and antitumor activities of native full-length melittin.

Based on the open-source single-cell RNA sequencing dataset, this study clarified CK's role in alleviating podocyte injury in MRL/lpr mice by regulating cytoskeleton-mediated mitochondrial fission and elucidated the molecular mechanisms underlying the BA receptor-YAP axis. MRL/lpr mice were administered CK (20 or 40 mg/kg) for 10 weeks. Renal function and pathological changes were evaluated, along with renal metabolite profiles and metabolomics analysis. We analyzed publicly available single-cell RNA sequencing data to specifically profile gene mapping and enrichment analysis during immune-mediated renal injury. Furthermore, podocyte-based in vitro assays were conducted to investigate the impact of the BA receptors-YAP axis on mitochondrial dynamics. CK effectively cleared anti-dsDNA antibodies, attenuated systemic inflammation, and improved renal function through resolving immune complex deposition. Mechanistically, CK restored actin cytoskeleton integrity via Rho GTPase regulation and reshaped BA metabolism to activate TGR5/FXR receptors in podocytes. This dual action suppressed DRP1 s616 phosphorylation, inhibiting excessive mitochondrial fission, regulating while enhancing TFAM-mediated mtDNA replication for mitochondrial homeostasis. Concurrently, CK attenuated podocyte apoptosis through Hippo signaling inhibition and YAP activation.

Current treatment strategies primarily provide symptomatic relief without effectively targeting the complex and multifactorial pathogenesis of NDDs, which involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and abnormal protein aggregation. Therefore, there is an urgent need for novel, multi-target therapeutic strategies. In recent years, marine biodiversity has gained growing attention as a rich reservoir of pharmacologically active natural products. Marine algae, in particular, contain diverse bioactive metabolites including polyphenols, polysaccharides, carotenoids, and phlorotannins, many of which exhibit potent neuroprotective properties. To address the existing knowledge void and limitations, we propose to present a thorough review that updates information on the neuroprotective effects of marine algal compounds and their therapeutic advancements. For this, about 31800 articles were reviewed via databases like PubMed, Science Direct, Google Scholar, and Web of Science. They were reduced to 1263 using MeSH words like 'marine algae, neurodegeneration, and neuroprotection' coupled with Boolean operators. The compiled findings demonstrated that marine algal compounds modulate multiple neuroprotective pathways, including PI3K/Akt, Nrf2/HO-1, and PKA/CREB/BDNF, and exert antioxidant, anti-inflammatory, anti-amyloidogenic, and neurotrophic effects. These multifaceted mechanisms highlight their potential in mitigating key pathological processes associated with NDDs.
