Don't give sugar to the immunodeficiency virus!

Virologists have found out that the HIV virus's craving for sweets can be used for the benefit of the body of AIDS patients – blocking the entry and assembly of sugar molecules into immune cells deprives the pathogen of the ability to copy itself, which prolongs the life of infected people.

Another target for the treatment of diabetic retinopathy

In addition to the already known vascular growth factor, another signaling protein, angiopoietin–4, is involved in the destruction of the retina in diabetes, which is also involved in the appearance of new vessels, and that their blocking successfully prevents the growth of defective capillaries.

Brain cancer vaccine: the result is not final, but encouraging

"I don't have an answer whether it is possible to achieve complete disappearance of the tumor by continuing this treatment. But a patient with a similar glioblastoma, who was treated the same way as you, has been alive for six years," the American doctor told his Russian patient.

How to overcome the ineffectiveness of melanoma immunotherapy

In some patients, cancer cells produce molecules that "scare away" cells of the immune system. After injection of dendritic cells into the tumor, T-lymphocytes began to actively penetrate there, and the use of immunotherapeutic drugs gave results.

Two more nucleotides were added to the genetic alphabet

The authors of the study have already synthesized DNA consisting of six nucleotides – the usual G, A, C and T, as well as new ones – Z and P. Scientists hope that their research data will expand the possibilities of synthetic biology.
