Scientists find Powerhouses that fight Tumours from within
In recent years, doctors have turned to a new treatment for cancer, immunotherapy, which works by leveraging the body's immune system to fight tumours.
The technique has largely focused on white blood cells called T-cells, which are "trained" to recognise and attack cancer cells.
But the innovative treatment only works well for around 20% of patients, and researchers have been trying to understand why some people respond better than others.
Three papers published on Thursday in the journal Nature point the way, identifying a key formation inside some tumours: tertiary lymphoid structures (TLS).
These structures function like "factories or schools" for immune cells that help the body fight cancer, said Wolf H. Fridman, a professor emeritus of immunology at the Cordeliers Research Centre of the Paris Descartes University medical school, who helped lead one of the studies.
"The cells need to be educated in schools, which are the tertiary lymphoid structures," where they effectively learn to recognise and attack cancer cells, Fridman told AFP.
No longer 'innocent bystanders'
Key to the findings is that T-cells are far from the only immune cells capable of taking the fight to cancer, with researchers finding the TLS were full of B-cells, a kind of immune cell that produces antibodies.
The purpose of this Research Topic is therefore to provide an up-to-date overview of cell interaction studies.
Areas of Study
Immunogenetics publishes original papers, brief communications, and reviews on research in the following areas: Genetics and evolution of the immune system; genetic control of immune response and disease susceptibility; bioinformatics of the immune system; structure of immunologically important molecules; and immunogenetics of reproductive biology, tissue differentiation, and development.
Immunogenetics: Open Access are welcoming experts in the fields of Genetics as well as immunology to submit Research, review articles, case reports and short communication summarizing the latest insights into immune responses and/or therapies (immunological and non-immunological) of Immune disorders, including: Systemic Lupus Erythmatosus, Crohn's disease and Rheumatoid arthritis.
A standard editorial manager system is utilized for manuscript submission, review, editorial processing and tracking which can be securely accessed by the authors, reviewers and editors for monitoring and tracking the article processing. Manuscripts can be uploaded online at Editorial Tracking System or forwarded to the Editorial Office at firstname.lastname@example.org.
