Pharmaceuticals (Basel, Switzerland)

Dawgul M, Baranska-Rybak W, Piechowicz L, Bauer M, Neubauer D, Nowicki R, Kamysz W.
PMID: 27231918
Pharmaceuticals (Basel). 2016 May 25;9(2). doi: 10.3390/ph9020030.

Staphylococcus aureus (SA) colonizes the vast majority of patients with atopic dermatitis (AD). Its resistance to antibiotics and ability to form biofilms are the main origins of therapeutic complications. Endogenous antimicrobial peptides (AMPs) exhibit strong activity against SA, including...

Association Between PTPN22 Polymorphisms and IgE Responses to Staphylococcal Superantigens in Chronic Urticaria.

Allergy, asthma & immunology research

Palikhe S, Kim SH, Pham le D, Ye YM, Park HS.
PMID: 25749762
Allergy Asthma Immunol Res. 2015 May;7(3):290-4. doi: 10.4168/aair.2015.7.3.290. Epub 2014 Oct 15.

Protein tyrosine phosphatase-22 (PTPN22) gene encodes lymphoid-specific tyrosine phosphatase (Lyp), an inhibitor of T cell activation. A polymorphism of the PTPN22 gene has been found to be associated with chronic urticaria (CU). We investigated the associations between PTPN22 gene...

PURPOSE: One of the advanced cancer therapy strategies is immune-stimulating compound based immunotherapy Staphylococcal enterotoxin B (SEB) is one of the potent superantigens, which can efficiently activate antitumor immune response to eradicate tumor growth and inhibit metastasis. Herein, we...

Central paraneoplastic neurological syndromes. Part 2. Practical, theoretical and mechanistic considerations of treatment with drugs and biologicals.

Drugs of today (Barcelona, Spain : 1998)

Pranzatelli MR.
PMID: 15010712
Drugs Today (Barc). 1998 Jun;34(6):507-23. doi: 10.1358/dot.1998.34.6.485248.

New information about paraneoplastic neurological syndromes, or the remote effects of cancer, has raised more questions than answers. The underlying mechanisms of brain injury remain to be elucidated. A brief review of autoimmunity provides a basis for exploring hypotheses...

Therapeutic Approaches to Streptococcal Toxic Shock Syndrome.

Current infectious disease reports

Baracco GJ, Bisno AL.
PMID: 11095793
Curr Infect Dis Rep. 1999 Aug;1(3):230-237. doi: 10.1007/s11908-999-0024-4.

The streptococcal toxic shock syndrome (STSS) is a severe, life-threatening condition characterized by hypotension and multiorgan system dysfunction associated with infection by the group A Streptococcus (GAS) or rarely by streptococci of other Lancefield serogroups. It is associated with...

Superantigens and autoimmune disease: are they involved?.

Current opinion in infectious diseases

Sawitzke AD, Mu HH, Cole BC.
PMID: 17035782
Curr Opin Infect Dis. 1999 Jun;12(3):213-9. doi: 10.1097/00001432-199906000-00010.

In over 10 years since the definition of superantigens, much has been learned about host cell-superantigen interactions. The initial simple set of rules used to define these interactions has given way to a more complex system, in which the...

Overexpressed Bcl-x(L) prevents bacterial superantigen-induced apoptosis of thymocytes in vitro.

Cell death and differentiation

Takahashi T, Honda H, Hirai H, Tsujimoto Y.
PMID: 16465222
Cell Death Differ. 1997 Feb;4(2):159-65. doi: 10.1038/sj.cdd.4400214.

bcl-x, a homologous gene of bcl-2, has an anti-apoptotic function and appears to play a critical role in the development of lymphoid systems. To investigate the effect of overexpressed Bcl-x(L) on the development of T lymphocytes, we established two...

HLA allele associations and V-beta T-lymphocyte expansions in patients with psoriasis, harboring toxin-producing Staphylococcus aureus.

Journal of biomedicine & biotechnology

Ajib R, Janbazian L, Rahal E, Matar GM, Zaynoun S, Kibbi AG, Abdelnoor AM.
PMID: 16489264
J Biomed Biotechnol. 2005;2005(4):310-5. doi: 10.1155/JBB.2005.310.

HLA alleles have been associated with psoriasis. Toxin-producing strains of Staphylococcus aureus behave as superantigens, and if present in patients, might play a role in the exacerbation of psoriatic lesions by activating certain V-beta (V beta) T-lymphocyte subsets. Allele...
