Lysozyme C
experimentalAlso known as: 1,4-beta-N-acetylmuramidase C, LYZ, P61626
Lysozyme C (1,4-beta-N-acetylmuramidase C, LYZ) exerts its primary mechanism of action through the hydrolysis of the β-1,4 glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in bacterial peptidoglycan, leading to cell lysis. Beyond direct bacteriolytic activity, lysozyme C is associated with the monocyte-macrophage system and is thought to enhance the activity of immunoagents, including opsonins and complement, thereby modulating innate immune responses. This dual role positions lysozyme C as both a direct antimicrobial agent and an immunomodulatory molecule. Key research findings indicate that lysozyme C is widely distributed in tissues and body fluids, with elevated levels observed during inflammatory and infectious states. Experimental studies have explored its potential in reducing bacterial load, particularly against Gram-positive pathogens, and its synergistic effects with other antimicrobial peptides or antibiotics. Additionally, lysozyme C has been investigated for its role in wound healing and mucosal defense, though its therapeutic applications remain largely preclinical. Clinically, lysozyme C is considered an experimental agent with no approved therapeutic indications. Its relevance lies primarily in its potential as an adjunctive treatment for infections or inflammatory conditions, but robust human trials are lacking. Further research is needed to establish safety, efficacy, and dosing parameters for any clinical application. For research purposes only — not medical advice.

CCR2+ macrophages transition from homeostatic to proinflammatory roles in obesity-induced cardiac dysfunction.; Inducible ablation of CCR2+CX3CR1+ macrophages or deletion of macrophage CCR2 prevents obesity-induced cardiac dysfunction.; Lysozyme 1 acts as a noncanonical transcription activator by binding to the RelA promoter, driving NF-κB signaling and inflammation.; Lysozyme 1 is a potential target for diagnosing and treating obesity-induced heart disease.
MFGs consist of a triacylglycerol core and a triple membrane containing polar lipids, proteins, glycoproteins, and cholesterol.; MFGs release energy rapidly in the upper gastrointestinal tract and persist to convey bioactive molecules to the colon.; Human and ruminant MFGs differ in size, composition, and specific constituents.; MFGs may be used to enhance neurodevelopment, defend against infections, improve insulin sensitivity, and treat inflammation.
SVLLP is a glycoprotein with three glycoforms sharing the same protein core but different N-linked glycans.; SVLLP lacks lysozyme activity due to a mutation (N53S) in one of two essential catalytic residues.; SVLLP is primarily expressed in seminal vesicles and is not regulated by testosterone.; SVLLP suppresses sperm capacitation, inhibits the acrosome reaction, and blocks sperm-oocyte interactions.
Lysozyme c-1 mRNA is constitutively expressed in the mosquito heart but overexpressed after bacterial injection.; A 14 kDa protein with lytic activity against M. luteus was detected in heart extracts.; mRNA-FISH showed specific hybridization signal in pericardial cells of M. luteus-injected mosquitoes.; This is the first report of an inducible immune factor in Anopheles albimanus pericardial cells.
