Abstract Summary
New research reveals that Panton-Valentine Leukocidin (PVL), a toxin produced by community-associated MRSA, causes severe muscle damage through inflammatory responses rather than direct cell killing. Using mutant CA-MRSA strains, scientists found PVL triggers muscle injury by recruiting neutrophils and releasing inflammatory chemicals, particularly affecting young patients with strong immune systems.
Why Brain? ðŸ§
Study reveals Panton-Valentine Leukocidin toxin in drug-resistant staph causes severe muscle damage through inflammation, not direct cell killing, explaining why young patients suffer worse infections.
