Staphylococcal Exfoliative Toxins in Cutaneous Infections
Summary
Staphylococcal exfoliative toxins are a family of serine proteases secreted by certain strains of Staphylococcus aureus that specifically cleave desmoglein-1 in the superficial epidermis. This targeted proteolysis disrupts keratinocyte adhesion, resulting in intraepidermal cleavage and the characteristic blistering of staphylococcal scalded skin syndrome (SSSS) and bullous impetigo. Exfoliative toxins ETA and ETB are regulated by the accessory gene regulator system, coordinating toxin expression with bacterial density. These toxins underpin both the localized lesions of bullous impetigo and the widespread epidermal desquamation seen in SSSS, which predominantly affects neonates and immunocompromised adults. Advances in structural biology have elucidated the molecular determinants of toxin–substrate specificity, while immunological studies have begun to characterise the host response and potential neutralising antibody epitopes. Clinically, accurate differentiation from other blistering dermatoses is vital, as rapid initiation of anti-staphylococcal therapy markedly improves outcomes. Emerging insights into toxin regulation, host susceptibility factors and potential vaccine candidates promise to inform next-generation preventive and therapeutic strategies, thereby addressing the global burden of toxin-mediated cutaneous disease.

Staphylococcal Exfoliative Toxins in Cutaneous Infections publication trend
The graph below shows the total number of articles in staphylococcal exfoliative toxins in cutaneous infections across all publications each year (not limited to Nature Index journals).
Technical terms
Exfoliative toxins: Serine proteases produced by S. aureus that cleave desmoglein-1 in the superficial epidermis, causing blister formation.
Desmoglein-1: A cadherin family adhesion protein in the epidermis that maintains keratinocyte cohesion; its cleavage leads to epidermal splitting.
Staphylococcal scalded skin syndrome (SSSS): A systemic toxin-mediated disease characterised by widespread epidermal desquamation and tenderness, predominantly in neonates.
Bullous impetigo: A localized superficial skin infection in which exfoliative toxins induce vesicles and bullae, typically in children.
Community-associated MRSA (CA-MRSA): Methicillin-resistant S. aureus strains acquired outside healthcare settings, often linked to skin and soft tissue infections.
Healthcare-associated MRSA (HA-MRSA): MRSA strains associated with hospital environments, notable for broader antibiotic resistance profiles.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
Nature Index 2026 Regenerative medicine
Regenerative medicine has the potential to transform the treatment of chronic and life-threatening diseases. But major challenges remain, such as overcoming immune rejection and ensuring that new therapies are developed using more inclusive data sets. In this supplement, we explore the discoveries that are driving the field, the barriers that could limit its progress, and the teams and institutions that are making their mark.
