The effects of Ostertagia occidentalis somatic antigens on ovine TLR2 and TLR4 expression

Iranian Journal of Parasitology, 2015
Background: Recognition of helminth-derived pathogen associated molecular patterns (PAMPs) by pattern recognition receptors (PRRs), including toll like recep­tors (TLRs) is the first step towards initiating anti–helminth immune re­sponses.

Characterization of the O antigen gene cluster and structural analysis of the O antigen of Francisella tularensis subsp. tularensis [PDF]

Journal of Medical Microbiology, 2003
A gene cluster encoding enzymes involved in LPS O antigen biosynthesis was identified from the partial genome sequence of Francisella tularensis subsp. tularensis Schu S4. All of the genes within the cluster were assigned putative functions based on sequence similarity with genes from O antigen biosynthetic clusters from other bacteria.

Shigella flexneriO-antigens revisited: final elucidation of the O-acetylation profiles and a survey of the O-antigen structure diversity [PDF]

FEMS Immunology & Medical Microbiology, 2012
Shigella flexneri is an important human pathogen causing shigellosis. Strains of S. flexneri are serologically heterogeneous and, based on O-antigens, are currently classified into 14 types. Structures of the O-antigens (O-polysaccharides) of S. flexneri have been under study since 1960s but some gaps still remained.

Reações locais e níveis de antitoxina circulante decorrentes de administração do toxóide tetânico: estudo comparativo entre Ped-o-Jet e seringa hipodérmica Local reactions and antitoxin levels induced by the administration of tetanus toxoid: a comparative study between Ped-o-Jet and hypodermic syringe

Revista de Saúde Pública, 1985
Com o objetivo de comparar reações locais e conversão sorológica apresentadas por adultos que receberam o toxóide tetânico através de Ped-o-Jet (via subcutânea) ou de seringa hipodérmica (via intramuscular), o toxóide foi administrado a 472 recrutas do ...

Polysaccharide-conjugate vaccines for Burkholderia pseudomallei based on the O-antigens of serotypes A and B

Carbohydrate Polymer Technologies and Applications
Burkholderia pseudomallei, a facultative intracellular pathogen, has been classified into three distinct serotypes: A, B, and B2. Serotype A is the most prevalent, serotype B is the next most common. However, no vaccines target B.

Enzymatic conversion of blood group B kidney prevents hyperacute antibody-mediated injuries in ABO-incompatible transplantation

Nature Communications
Matching ABO blood group antigens between donors and recipients is critical to prevent hyperacute rejection in kidney transplantation. Enzymatic conversion of blood group antigens to the universal O type presents a promising strategy to overcome barriers

Tumor-associated Tn and STn antigens: from molecular mechanism to precision diagnosis and treatment

Frontiers in Immunology
BackgroundAbnormal protein glycosylation is a key feature of tumors. Among the modifications, Tn antigen (GalNAcα1-Ser/Thr) and its sialylated derivative, STn antigen (Neu5Acα2-6GalNAcα1-O-Ser/Thr), are prominent tumor-associated carbohydrate antigens ...
