We have analysed the influence of size, intracellular localisation, and sorting of various human immunodeficiency virus type 1 (HIV-1)-derived Gag and Env polypeptides containing well defined H2(d)-restricted cytotoxic T lymphocyte (CTL) epitopes on the induction of a humoral and cellular immune response after DNA vaccination. Thus, expression vectors were generated based on RNA- and codon-opti...
background: naltrexone, an opioid receptor antagonist shifts the immune response toward a th1 profile. in the current study, we evaluated the efficacy of the mixture of ntx and alum, as a new adjuvant, to enhance immune response and induce protection against leishmania major in a mouse model. methods : balb/c mice were immunized three times either autoclaved l. major promastigotes’ antigens alo...
Photorefractoriness (PR) in the turkey breeder hen is characterized by a lack of responsiveness to photoperiods that previously induced or maintained egg production. The consequence of PR is spontaneous regression of ovarian function and cessation of lay. Photosensitivity (PS) may be regained by giving at least 8 wk of short photoperiod (8L:16D) (light restriction). Following the transition fro...
BACKGROUND Previous exposures to flu and subsequent immune responses may impact on 2009/2010 pandemic flu vaccine responses and clinical symptoms upon infection with the 2009 pandemic H1N1 influenza strain. Qualitative and quantitative differences in humoral and cellular immune responses associated with the flu vaccination in 2009/2010 (pandemic H1N1 vaccine) and natural infection have not yet ...
As previously reported, inflammatory activity initiated by intradermal injection of multiple growing feather (GF)-pulps a chicken with lipopolysaccharide, and the subsequent periodic sampling GFs blood, enables longitudinal evaluation in vivo tissue- systemic-inflammatory activities ex laboratory analyses. To demonstrate suitability this two-window approach to monitor assess vaccine responses, ...
We previously reported differential humoral responses to glucosyltransferases (GTFs), with significantly higher saliva and serum antibody levels to GtfD than to GtfB or GtfC. To test the hypothesis that cellular immune responses to these molecules also may differ, peripheral blood mononuclear cell (PBMC) and T-cell proliferative responses in young adults and children with distinct genetic backg...
