Transplantation without immunosuppressants and without organ rejection

Researchers from King's College in London prevented the rejection of the transplant by the immune cells of the recipient animal. At the same time, the immune system has not lost its ability to fight infection and degenerated (atypical, cancerous) cells.

Just one gyrus – not from the cap, but because of a "defective" gene

Replacing just two nucleotides in the gene of one of the cell membrane proteins, laminin gamma 3 (LAMC3), can turn a genius into an idiot: this mutation leads to underdevelopment of the convolutions in the cerebral cortex.

Molecular biological agent for hair growth

Hair follicle stem cells coordinate hair regeneration using two molecular signals: a WNT activator and a BMP inhibitor. The researchers who discovered this signaling pathway are already patenting a new method for modulating hair growth.

The key gene causing diabetes and obesity has been calculated

Everyone has the KLF14 gene, regardless of blood glucose levels, body weight and other factors. But its activity in diabetes or obesity is higher – the protein that encodes this gene is synthesized more in patients.

Displacement of old age

In a rapidly aging world, aging people are treated badly, sometimes even extremely badly. And here is one of the reasons that people try not to get old. Or at least not look aging (not to mention "old").

Will disabling Rasip1 protein synthesis help to suffocate the tumor?

Chemical compounds that suppress the activity of Rasip1 can probably resist the development of cancer in two ways: through disruption of the nutrition of tumor tissue cells and disruption of the transport system of degenerated cells.

Unhappy childhood shortens life

When comparing the DNA of orphaned children who grew up in an orphanage or foster families, it turned out that the telomeres, the chromosomal clock that determines the life of a cell, shorten faster in the former.

Genetically modified virus for early cancer diagnosis

Biotechnologists have taught the herpes virus to recognize cancer cells. The mutant virus infects atypical cells, which causes them to turn green and glow. According to herpetic "fireflies", scientists find tumors and metastases.
