Generation of virus-specific cytotoxic T cells in vitro I. Induction conditions of primary and secondary Sendai virus-specific cytotoxic T cells [PDF]

open access: yes, 1979
H-2-restricted cytotoxic T cells specific for Sendai virus were generated in vitro in a primary response from normal mouse lymphocytes cultured in the presence of infective as well as inactivated Sendai virus. Antigen-presenting cells of different origin,

Role of early viral surface antigens in cellular immune response to vaccinia virus [PDF]

open access: yes, 1976
Infection of mice with the vaccinia virus strain WR, Elstree or DIs, a conditional lethal mutant of vaccinia virus, resulted in the generation of vaccinia virus-specific sensitized cytolytic T lymphocytes (CTL).

Chemoenzymatically Synthesized O‐Acetylated GD3 Gangliosides to Examine Viral Receptor Specificities in a Cellular Context

open access: yesAngewandte Chemie, EarlyView.
7‐O‐, 9‐O‐, and 7,9‐di‐O‐acetylated GD3 gangliosides can be prepared by chemical assembly of a tetrasaccharide as α‐glycosyl fluoride that is coupled to sphingosine using a glycosynthase, followed by O‐acetyl editing by coronaviral hemagglutinin‐esterases (HEs).

Improvement of the indirect hemagglutination test for the detection of antibodies to Streptococcus pyogenes

open access: yesBrazilian Journal of Medical and Biological Research, 1998
An indirect hemagglutination test for a seroepidemiological survey of Streptococcus pyogenes infection was standardized. This is an improved modification of the indirect hemagglutination test which utilizes an unstable reagent prepared with fresh blood ...

Cross-protection against European swine influenza viruses in the context of infection immunity against the 2009 pandemic H1N1 virus : studies in the pig model of influenza [PDF]

open access: yes, 2015
Pigs are natural hosts for the same influenza virus subtypes as humans and are a valuable model for cross-protection studies with influenza. In this study, we have used the pig model to examine the extent of virological protection between a) the 2009 ...

Sensitive detection systems for infectious agents in xenotransplantation*

open access: yesXenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Evidence of Burkholderia pseudomallei-Specific Immunity in Patient Sera Persistently Nonreactive by the Indirect Hemagglutination Assay

open access: yesClinical and Vaccine Immunology, 2011
The indirect hemagglutination assay (IHA) is the most frequently used serological test to confirm exposure to Burkholderia pseudomallei. Patients with culture-confirmed disease often have a nonreactive IHA at presentation and occasionally fail to ...
