Abstract Streptococcus pyogenesis a significant cause of infectious morbidity and mortality globally. Antibiotics remain the essential treatment for S. pyogenesinfection however, as resistance against long-used antibiotics grows amongst bacterial pathogens antibiotic failure becomes increasingly common in pyogenestreatment, necessity alternative methods escalates. Here, we have selected conserv...
Abs confer protection from secondary infection with Legionella pneumophila, the causative agent of a severe form of pneumonia known as Legionnaires' disease. In this study, we demonstrate that Ab-mediated protection is effective across L. pneumophila serogroups, suggesting that Abs specific for conserved protein Ags are sufficient to mediate this protective effect. We used two independent metho...
The infection mechanism of vaccinia virus is largely unknown. Neither the attachment protein of extracellular enveloped virus (EEV), the biologically relevant infectious form of the virus, nor its cellular receptor has been identified. Surprisingly, all former attempts using antibodies to block EEV infection of cells in vitro had failed. Here, we report the production of an anti-envelope hyperi...
Background: Tumor cells express antigens that can be recognized by immune system as foreign particles. Heat shock proteins (HSPs) are molecular chaperones that bind to tumor antigens and mediate their uptake into antigen presenting cells. Methods: This articles is a review article and its data has been collected and categorized from the articles in the field of cancer immunotherapy. All the ar...
Influenza viruses continue to be a major health threat in human and bird populations. The improvements in formulation and production level of the current influenza vaccines are not sufficient to afford complete protection. The continuous antigenic drifts and emergence of endemic and zoonotic strains make influenza vaccine planning difficult. Concern about the emergence of new influenza pandemic...
