Multiple sclerosis receives experimental treatment

Multiple sclerosis receives experimental treatment

The results were promising compared to the conventional treatments available today. In a group of 52 patients, only 3 presented some worsening in their condition three years after the procedure, unlike the control group, which in a total of 50 patients, 30 worsened.

The treatment aims to cease the attack immune system to brain cells with a radical approach: their destruction and reconstruction. "We are not trying to regenerate the neurons, what we are trying to do is to get the immune system to stop attacking the brain to allow it to recover," said Richard Burt, project leader in an interview for the O Globo newspaper. What is it?

Multiple sclerosis is an autoimmune disease that affects the brain, optic nerves, and spinal cord (central nervous system). This is because the body's immune system confuses healthy cells with "intruders," and attacks them by causing injuries. The patient's immune system erodes the protective nerve sheath known as myelin. Myelin damage causes interference in communication between the brain, spinal cord and other areas of the central nervous system.

How is the experimental treatment performed?

In therapy, hematopoietic stem cells are collected from the patient, present in the blood and in the bone marrow, which are only able to differentiate into blood cells (red blood cells, white blood cells, etc.).

Next, potent chemotherapeutic drugs are given for the total removal of the person's immune system, ceasing inflammation in the brain . Then, the collected hematopoietic stem cells are injected back into the patient so that they rebuild the immune system.

Preventing mosquito bites prevents diseases like malaria and dengue

Dengue, yellow fever, malaria, filariasis, leishmaniasis. Did you know that all these diseases are transmitted by mosquitoes? These mosquitoes function as a vector, that is, they transmit the disease. The mosquito Aedes aegypti is now a vector of three diseases in Brazil: zika virus, dengue fever and chikungunya fever.
