Scientists find a new use for already known anti-cancer drugs

The world clinical neighborhood is waging a tough and extended war on cancer. New research study in the field of immunogenic cell death can extend the location of drugs application and make sure clients’ security from regression after treatment.

Cancer treatment is not simply the elimination of the growth cells from the body, and chemotherapy. The physicians’ objective is to supply a situation that would avoid growth cells from multiplying and triggering a new illness.

For several years, scientists at the Lobachevsky State University of Nizhny Novgorod and the University of Ghent (Belgium) have actually been participated in research study intended to lessen the damage to the body after cancer treatment and have actually been looking for new approaches to dealing with cancer clients.

The job, supported by a grant from the Russian Science Foundation and headed by Dmitry Krys’ko, leading scientist of the Lobachevsky University’s Institute of Biology and Biomedicine, teacher at Ghent University, has actually yielded its very first significant outcomes.

According to Professor Dmitry Krys’ko, the existing anti-cancer treatment (chemotherapy, radiation treatment and photodynamic treatment) triggers fantastic damage to the body as a whole, while his group’s research study is focused on the stimulation of immunogenic cell death, which not just decreases the damage, however likewise improves the effectiveness of treatment by including the body’s resources in the battle versus cancer.

“In this research study, we checked some drugs for anticancer treatment based upon photodynamic treatment and examined their new immunogenic residential or commercial properties. We can state that not just the external effect will be utilized to eliminate cancer, however likewise the body itself will take part in the battle by activating the responses of the adaptive immune action.

The idea of immunogenic cell death (ICD) consists of a set death of cancer cells with subsequent release of particles that offer a threat signal to the body immune system. We checked the drugs that are already utilized in cancer treatment, and improved the action of these representatives,” stated Professor Krys’ko.

The research study used a variety of approaches and techniques that were utilized in in vitro and in vivo experiments. At the labs of Lobachevsky University and the University of Ghent, scientists studied how compounds collect in the cell, examined cell death types when cells were exposed to photosensitizers, and exposed molecular systems of the phenomena that strike the cells in the procedure of their death.

“In this study, we examined the cellular-level response of dendritic cells (immune system components) in their interaction with cancer cells that were exposed to photodynamic therapy (PDT) and proved that photodynamic therapy can activate the body’s own immune response,” stated Victoria Turubanova, research study assistant of the Department of General and Medical Genetics at the UNN Institute of Biology and Biomedicine.

The scientists have actually analyzed extra elements of the use of existing drugs for establishing new cancer procedures based upon the stimulation of the body immune system. Such versions of treatment minimize the threat of transition and improve the efficiency of the client’s healing.

A series of experiments on lab mice was carried out, leading to a crucial conclusion that the cellular vaccine prepared from passing away cancer cells secures the mouse from cancer by avoiding growth advancement in the body.

Based on the outcomes gotten, the scientists have actually released their post «Immunogenic cell death caused by a new photodynamic treatment based upon Photosens and Photodithazine» in the BMC Journal for ImmunoTherapy of Cancer (with the effect element of 8.67), which explains new versions of photosensitizers that trigger immunogenic cell death of cancer cells.
