Isolation, Cloning, and Expression of Streptococcus dysgalactiae Subspecies Superantigen by SDS-PAGE in Psoriasis Patients

مجله دانشگاه علوم پزشکی گرگان, 2022
Background and Objective: Streptococci are Gram-positive and anaerobic bacteria that are isolated from different sources. These bacteria are capable of producing superantigens, toxins, and biologically-active substances and are therefore very important ...

Staphylococcal Superantigen (TSST-1) Mutant Analysis Reveals that T Cell Activation Is Required for Biological Effects in the Rabbit Including the Cytokine Storm

Toxins, 2010
Staphylococcal superantigens (sAgs), such as toxic shock syndrome toxin 1 (TSST-1), induce massive cytokine production, which may result in toxic shock syndrome (TSS) and sepsis.

Immune cell activation by enterotoxin gene cluster (egc)-encoded and non-egc superantigens from Staphylococcus aureus

, 2008
The species Staphylococcus aureus harbors 19 superantigen gene loci, six of which are located in the enterotoxin gene cluster (egc). Although these egc superantigens are far more prevalent in clinical S.

Sleeping with the Enemy— Endogenous Superantigens in Humans [PDF]

, 2001
We usually think of superantigens (SAg) as dangerous toxins that may cause toxic shock syndrome and death (Marrack and Kappler, 1990). Now, based on two papers in this issue of Immunity, it seems that we all have SAg genes within us, lying dormant and ...

Superantigens and nasal polyps

, 2003
Nasal polyps represent an often severe T-cell-orchestrated eosinophilic upper airway disease with currently unknown pathogenesis, often associated with lower airway disease, such as asthma. Superantigens, predominantly derived from Staphylococcus aureus,
