Neuroprotective Activity of Melittin—The Main Component of Bee Venom—Against Oxidative Stress Induced by Aβ25–35 in In Vitro and In Vivo Models

open access: yesAntioxidants, 2021
Melittin, a 26-amino acid peptide, is the main component of the venom of four honeybee species and exhibits neuroprotective actions. However, it is unclear how melittin ameliorates neuronal cells in oxidative stress and how it affects memory impairment ...

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

open access: yesFood Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

Helical Structure of Recombinant Melittin [PDF]

open access: yesThe Journal of Physical Chemistry B, 2018
Melittin is an extensively studied, 26-residue toxic peptide from honey bee venom. Because of its versatility in adopting a variety of secondary (helix or coil) and quaternary (monomer or tetramer) structures in various environments, melittin has been the focus of numerous investigations as a model peptide in protein folding studies as well as in ...

Highly Synergistic Effects of Melittin With Vancomycin and Rifampin Against Vancomycin and Rifampin Resistant Staphylococcus epidermidis

open access: yesFrontiers in Microbiology, 2022
Methicillin-resistant Staphylococcus epidermidis (MRSE) strains are increasingly emerging as serious pathogens because they can be resistant to many antibiotics called multidrug resistance (MDR) that limit the therapeutic options.

Targeting the intratumoral microbiota to overcome cancer immunotherapy resistance

open access: yesInterdisciplinary Medicine, EarlyView.
This review delineates the mechanisms of intratumoral microbiota in cancer immunotherapy resistance, and offers strategies for microbiota‐targeted precision immunotherapy. Abstract Cancer remains a significant global health threat. The tumor microenvironment (TME) is a sophisticated ecological niche that exerts a pivotal effect on treatment outcomes ...

The Protective Effect of Melittin on Renal Fibrosis in an Animal Model of Unilateral Ureteral Obstruction

open access: yesMolecules, 2016
Renal fibrosis is the principal pathological process underlying the progression of chronic kidney disease that leads to end-stage renal disease. Melittin is a major component of bee venom, and it has anti-bacterial, anti-viral, and anti-inflammatory ...

Effects of melittin on laying performance and intestinal barrier function of quails

open access: yesPoultry Science, 2023
: To study the effects of melittin on egg-laying performance and intestinal barrier of quails, 240 quails (aged 70 d) were randomly divided into 4 groups with 6 replicates (10 quails per replicate). They were fed with basal diet (group B), basal diet + 0.

Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Survey of probable synergism between melittin and ciprofloxacin, rifampicin, and chloramphenicol against multidrug-resistant Pseudomonas aeruginosa

open access: yesFrontiers in Microbiology
BackgroundThe emergence of multidrug-resistant bacteria and also biofilm-associated infections is a great health concern due to the failure of available antibiotics. This has alerted scientists to developing alternative antibiotics.

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.
