Boosting the Immune System to Effect Repairs and Fight Disease

Applications from Regenerative Medicine to Gene Therapy to Antiviral Therapeutics Emphasize Self-Healing

Therapeutic interventions of various kinds try to improve the body’s capacity to defend, repair, and even cure itself. Interventions that attempt to enhance self-healing span cell-based therapy, gene therapy, small molecule drugs, biologics, and tissue engineering.

Advances in each of these areas are being followed by Allied Market Research, which has concluded that stem cell technologies look especially promising. For example, stem cell technologies are set to revolutionize the human ability to produce neural cells in abundance.

Immune cells self-healing brain after stroke

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

"This is in total contrast to our previous beliefs", says Professor Zaal Kokaia from Lund University in Sweden.

Zaal Kokaia, together with Professor of Neurology Olle Lindvall, runs a research group at the Lund Stem Cell Center that, in collaboration with colleagues at the Weizmann Institute in Israel, is responsible for these findings. Hopefully, these new data will lead to new ways of treating stroke in the future. The study was recently published in the Journal of Neuroscience.

When stroke occurs, the nerve cells in the damaged area of the brain die, causing an inflammation that attracts cells from the immune system. Among them you find monocytes—a type of white blood cells produced in the bone marrow.
