Characterization and expression analysis of Staphylococcus aureus pathogenicity island 3 - Implications for the evolution of staphylococcal pathogenicity islands [PDF]

, 2002
We describe the complete sequence of the 15.9-kb staphylococcal pathogenicity island 3 encoding staphylococcal enterotoxin serotypes B, K, and Q. The island, which meets the generally accepted definition of pathogenicity islands, contains 24 open reading

Discrimination between patients with acquired toxoplasmosis and congenital toxoplasmosis on the basis of the immune response to parasite antigens [PDF]

, 2000
Many persons infected with Toxoplasma gondii develop ocular lesions, Immunologic parameters in the response to I gondii were evaluated in infected persons with and without ocular lesions and in noninfected controls.

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, EarlyView.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...

Effectiveness of a screening protocol employed at a UK rescue centre to prevent introduction of strangles

Equine Veterinary Journal, Volume 58, Issue 2, Page 466-475, March 2026.
Abstract Background Infection with Streptococcus equi subspecies equi (S. equi) is characterised by acute disease, with about 10% of infected animals remaining persistently infected. Clinically, infection with S. equi cannot readily be distinguished from infection caused by other respiratory pathogens, including Streptococcus equi subspecies ...

Peripheral Blood Skin‐Homing T Cells Define Immunological Endotypes in Atopic Dermatitis: A Case–Control Study in a Mexican Population

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aims Atopic dermatitis (AD) is a chronic inflammatory skin disease with marked immunological heterogeneity. T‐cell subsets expressing CLA, CCR4, and CCR10 are involved in skin inflammation, but their frequency and expression patterns in AD remain poorly characterized.

Genomic analysis and identification of a novel superantigen, SargEY, in Staphylococcus argenteus isolated from atopic dermatitis lesions

mSphere
During surveillance of Staphylococcus aureus in lesions from patients with atopic dermatitis (AD), we isolated Staphylococcus argenteus, a species registered in 2011 as a new member of the genus Staphylococcus and previously considered a lineage of S ...

Chinese Guidelines for Diagnosis and Treatment of Chronic Rhinosinusitis (2024)

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 25-55, February 2026.
ABSTRACT Chronic rhinosinusitis (CRS), a complex inflammatory disease with heterogeneous pathogenesis, demands evolving evidence‐based strategies. Since the 2018 Chinese guidelines and EPOS2020, international advances in CRS immunopathology and biologics have revolutionized therapeutic approaches, particularly through phenotype–endotype classification ...

Phosphotyrosines in the killer cell inhibitory receptor motif of NKB1 are required for negative signaling and for association with protein tyrosine phosphatase 1C. [PDF]

, 1996
NKB1 is one member of a growing family of killer cell inhibitory receptors (KIR). It is expressed on natural killer (NK) cells and T cells, and has been shown to inhibit cytolytic functions of these cells upon interacting with its ligand, HLA-B (Bw4). We

MAIT cells launch a rapid, robust and distinct hyperinflammatory response to bacterial superantigens and quickly acquire an anergic phenotype that impedes their cognate antimicrobial function: Defining a novel mechanism of superantigen-induced immunopathology and immunosuppression [PDF]

, 2017
Superantigens (SAgs) are potent exotoxins secreted by Staphylococcus aureus and Streptococcus pyogenes. They target a large fraction of T cell pools to set in motion a "cytokine storm" with severe and sometimes life-threatening consequences typically ...
