Discovery of potential candidate protein for cancer vaccines

Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.

Medicago announces positive results for H1N1 pandemic vaccine candidate

Medicago today announced that it has achieved additional positive results with its vaccine candidate for the Influenza A (H1N1) virus, also known as Swine flu. Results showed that a single dose of 5 micrograms induced a positive immune response against a new emerging strain of this virus in 100% of vaccinated animals.

Immune responses to flu vaccine are diminished in lupus patients

Patients with the autoimmune disease systemic lupus erythematosus (SLE) have an increased risk of infection, due to both disturbances in their immune responses and treatment with immunosuppressive drugs.

Potential malaria transmission-blocking vaccine

Researchers at the Johns Hopkins Malaria Research Institute have for the first time produced a malarial protein (Pfs48/45) in the proper conformation and quantity to generate a significant immune response in mice and non-human primates for use in a potential transmission-blocking vaccine.

Researchers decipher special role of the messenger Beta-interferon for immune responses

Researchers from the Molecular Immunology group at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have now shown that Beta-Interferon also plays a crucial role during an immune response: without Beta-Interferon immune cells are unable to show "wanted posters" of pathogens to other cells.
