Vaccine for all diseases

Scientists from the Research Institute named after Ellen Scripps cured mice of two types of tumors at once with one vaccine and an additional injection: melanoma and colon cancer. Moreover, tumor resistance was only a demonstration of a new approach, which, according to the authors, with appropriate modification, will be suitable for HIV, influenza, and any other infections.

Who will get the medicines from the shelf?

According to Evgeny Sverdlov, the project manager for the development of the first domestic gene therapy drug against cancer, the appearance of innovative drugs under the brand "Made in Russia" in the coming years is unlikely. Prototypes of drugs that have already been created in our laboratories, which theoretically could compete with Western developments, are being shelved due to the lack of funds for clinical trials, patenting, licensing, production and promotion of drugs to the market.

Nanotechnology in medicine: successes and prospects

Recently, nanotechnology has been increasingly being introduced into many areas of human activity. This trend has not bypassed medicine. Today, macromolecules and artificially prepared particles are used for the diagnosis, treatment of various diseases and restoration of damaged tissues. The new direction was called nanomedicine. Russian scientists have achieved considerable success in this field.

Metabolomics against cancer

The term "metabolomics" is not yet as well known as genomics, the study of genes, or proteomics, the study of intracellular proteins. The study of prostate metabolites allowed us to find a marker with which it may be possible to detect prostate cancer by urine analysis.

Will the neurotrophic factor cure Alzheimer's disease?

Scientists from San Diego worked with several models of Alzheimer's disease, which was reproduced in mice, rats and monkeys. The experimenters either injected the neurotrophic factor itself into the affected tissues, or infected them with a harmless genetically engineered virus carrying an embedded gene for this protein. In all cases, the sick animals showed a significant improvement in the ability to memorize and learn.

Cancer Immunotherapy: Training dendritic cells

Dendritic cells by themselves do not destroy cancerous growths. They recognize specific proteins-antigens located on the surface of cancer cells, and then activate killer lymphocytes that directly attack the tumor. However, under normal conditions they do not do it very effectively. The task of immunotherapy is to make dendritic cells react strongly and precisely to the form of cancer that the patient suffers from.

Cancer, antioxidants and free radicals

Two oncology news: bad and good. Doctors again found no evidence that taking antioxidant vitamins helps prevent cancer. But another Achilles heel was found in tumors – an enzyme that enhances the synthesis of free radicals in cancer cells and simultaneously weakens their antioxidant mechanisms.

Autoimmune diseases and testosterone

Testosterone blocks the synthesis of molecules that stimulate the immune response. An intermediate agent of this mechanism can become a good target for the development of drugs against chronic inflammation, as well as asthma and other autoimmune diseases.
