Hepatitis virus used as a weapon against the rejection in transplant patients


According to research recently published by the journal Science Traslational Medicine, the hepatitis C virus (known as HCV) has become an interesting tool when faced with rejection in liver transplant patients.

As reported by the abovementioned study, 50% of people infected with hepatitis C (17 out of a total of 34) who underwent transplantation were able to maintain the performance of their new liver, even after they stopped taking immunosuppressive drugs – a type of drug administered to this type of patient so that their body does not recognise the transplanted organ as a foreign entity, with the risk of rejection that this implies.

This is a situation, which, in spite of the high percentage of patients in whom it works (50% of cases), has no clinical application. In view of the fact that the risk of rejection disappeared in one out of two patients - as shown in the investigation - hepatitis C infection could cause the rapid onset of cirrhosis in the transplanted organ. In any event, it is possible that this research may become a discovery that brings to light part of the unknown behaviour of our immune system. An investigation that offers not only new answers, but also new questions According to Read more

Artificial cornea transplants, an alternative to other methods

The cornea is a natural, transparent and outer lens, located at the front of our eye that covers the iris, pupil, and the anterior chamber.

It is an ocular tissue which acts as a window and has a number of basic properties for the quality of our vision. The cornea permits the light to enter the eye and it plays an important role in focusing images on the retina, therefore any alteration in its structure has adverse effects on our vision.

At the same time, the cornea becomes by its very nature a layer of protection for the internal ocular structures against possible external threats, whether physical, chemical or as a result of microbes. Artificial corneas: what the future holds As we have previously discussed in other entries on this blog, when it comes to replacing a human tissue we may choose to substitute it with a tissue generated in a laboratory. In this case we will delve into the developments achieved in the creation of artificial corneas which are able to replicate, in the most accurate and effective manner, the structure and Read more
