Life sciences

Life Sciences includes Health.

Life sciences, genomics and biotechnology for health -   Objective The activities carried out in this area are intended to help Europe exploit, by means of an integrated research effort, breakthroughs achieved in decoding the genomes of living organisms, more particularly for the benefit of public health and citizens and to increase the competitiveness of the European biotechnology industry. In the field of applications, the emphasis will be put on research aimed at bringing basic knowledge through to the application stage ("translational" approach) to enable real, consistent and coordinated progress at European level in medicine and improve the quality of life.

Justification of the effort and European added value "Post-genomic" research based on analysis of the human genome and genomes of other organisms, will culminate in numerous applications in various health-related sectors, and notably in the development of new diagnostic tools and new treatments capable of helping to combat diseases that are not at present under control, offering major potential markets. This research may also have implications on research on areas such as environment and agriculture.

In the medical field, the objective is to develop improved patient-oriented strategies for the prevention and management of disease and for living and ageing healthily. Furthermore, in this context, attention will be paid to childhood diseases and related treatments whenever appropriate. In addition, there is a particular priority for Europe to mobilise its efforts in a coordinated way towards combating cancer and confronting the major communicable diseases linked to poverty. This research will therefore concentrate on translating the new knowledge being created, which is not limited to genomics and other fields of basic research, into applications that improve clinical practice and public health.

To enable the Union to improve its position in this area and benefit fully from the economic and social spin-offs of the expected developments, as well as contribute to the international debate, it is necessary both to increase investment significantly and integrate the research activities conducted in Europe within a coherent effort.

Actions envisaged : 

The Community activities carried out to this end will address the following aspects. A. Advanced genomics and its applications for health (a) Fundamental knowledge and basic tools for functional genomics in all organisms: (i) gene expression and proteomics; (ii) structural genomics; (iii) comparative genomics and population genetics; (iv) bio-informatics; (v) multi-disciplinary functional genomics approaches to basic biological processes. (b) Application of knowledge and technologies in the field of genomics and biotechnology for health: (i) technological platforms for the developments in the fields of new diagnostic, prevention and therapeutic tools (including pharmacogenomic approaches, stem cell research and alternative methods to animal testing).

B. Combating major diseases (a) Application-orientated approach to medical genomics knowledge and technologies including the use of animal and plant genomics where relevant, mainly in the following fields(2): (i) combating diabetes, diseases of the nervous system (such as Alzheimer's disease, Parkinson's disease and new variant Creutzfeldt-Jakob disease and, where relevant, mental illness), cardiovascular diseases, and rare diseases; (ii) combating resistance to antibiotics and other drugs; (iii) studying human development, the brain and the ageing process. (b) A broader approach, not limited to genomics and other fields of basic research, will be pursued with regard to: (i) cancer, with a focus on the development of patient-oriented strategies from prevention to diagnosis and treatment, including three inter-linked components: - developing necessary networks and initiatives to coordinate national research activities, - supporting clinical research aimed at validating new and improved interventions, - supporting "translational" research; (ii) combating the three poverty-linked infectious diseases (AIDS, malaria and tuberculosis) which have priority in terms of disease control at Union and international level.
