PURPOSE Vaccine-induced antitumor CD8+ T-cell responses are believed to play an important role in increasing resistance to melanoma. The following study was conducted to examine whether these responses are associated with improved clinical outcome in melanoma vaccine-treated patients. EXPERIMENTAL DESIGN We measured CD8+ T-cell responses to gp100, MART-1, MAGE-3, and tyrosinase by enzyme-link...

Human influenza A(H3N2) viruses that predominated during the moderately severe 2014-2015 influenza season differed antigenically from the vaccine component, resulting in reduced vaccine effectiveness (VE). To examine antibody responses to 2014-2015 inactivated influenza vaccine (IIV) and live-attenuated influenza vaccine (LAIV) among children and adolescents, we collected sera before and after ...

The development of a tuberculosis (TB) vaccine that induces sterilizing immunity to Mycobacterium tuberculosis infection has been elusive. Absence of sterilizing immunity induced by TB vaccines may be due to delayed activation of mucosal dendritic cells (DCs), and subsequent delay in antigen presentation and activation of vaccine-induced CD4+ T-cell responses. Here we show that pulmonary delive...

PURPOSE Different vaccination strategies against the NY-ESO-1 antigen have been employed in an attempt to induce antitumor immune responses. Antigen-specific effector T-cell responses have been reported in a subset of vaccinated patients; however, these responses have not consistently correlated with disease regression. Here, we report for the first time clinical and immune responses generated ...

background: boophilus tick is responsible for the transmission of some pathogens (types of germs) and the reduction of fertility in cattles. tropomyosin protein plays an important role in regulating actin function, immune and allergic reactions and vaccine production. objectives: accurate identification of antigenic determinants (epitopes) is difficult, time consuming and not economic, thus we ...

Influenza is a vaccine preventable disease that causes severe illness and excess mortality in humans. Licensed influenza vaccines induce humoral immunity and protect against strains that antigenically match the major antigenic components of the vaccine, but much less against antigenically diverse influenza strains. A vaccine that protects against different influenza viruses belonging to the sam...
