The gene mutation that launched several forms of pancreatic cancer has been identified by scientists at the Karolinska Institutet in Sweden with the objective of finding a reliable and simple way to develop a vaccine that works against this form of the disease. The study which has just been published in the journal Cell aims to investigate this question in detail.
Pancreatic cancer is the most common type of cancer of the pancreas. It is characterized by a gradual progressive loss of pancreatic cells over time and the formation of fatty substances called lipofuscin inside the cancer cells. This disharmonious process is known as polyposis and is caused by constant inflammation of the cells during long-term infection. A very small molecule drug known as hA120 is available as an initially strong strong anti-cancer-1 (anti-PD-1) antibody.
Targeting of lipofuscin has generally been a good strategy for decreasing tumor size and destroying the cancer cells but it has been difficult to successfully immunize mice with this molecule – and especially since it is also present on the cell surface in the form of lipofuscin precursors – in the same way that the vaccine must be able to prevent tumours protein invasion into the surrounding tissues.
Systemic inflammation that occurs as a result of constant infection causes an important immunological balance that is impacted with cancer says first author Esben Agerbo researcher at the Department of Clinical Medicine and Surgery at Karolinska Institutet.
First things first how might the researchers need to cut short their study by reporting to the World Health Organization (WHO) is needed in order to develop a drug that can prevent cancer from returning inside the body?
After more than a decade of oral cancer our main breakthroughs are the development of MVP which is an immuno-oncogenic vaccine – a pathway that involves methodically identifying and inducing cancer cells says Ellen Hofer professor at the Department of Clinical Medicine and Surgery at Karolinska Institutet and Dr.
MVP will allow us for the first time to selectively kill pancreatic cancer cells which in the course of the next decade will allow us to develop a targeted cancer vaccine.
In addition we now for the first time also have a potential way to prevent cancer cells from invading your lymph nodes and other organs. And this is the reason why we are investing a months work when there was a difficult summer month to begin this new process concludes the researcher.
