Introduction
Immunology is the study of the cells and molecules that provide
an effective and highly specific response to a wide array of
foreign antigens. Knowledge of the mechanisms for coordination
and regulation of the immune system is an exciting and rapidly
advancing frontier with major implications for vaccine development
and treatment of immune disorders. There are several diseases
associated with disorders of the immune system. These include
allergy, autoimmunity and immunodeficiency such as following
HIV infection. Transplant rejection is also an example of an
unwanted immune response.
Recent insight into the molecular basis for these disorders
is leading the way to more effective and selective treatment.
Who Should Do This Course?
This course is ideal for a wide audience of professionals
in the life sciences sector including academics, research
scientists (Pharmaceutical Professionals, Biotechnologists,
etc.) and healthcare workers (medical specialists, nurses,
medical laboratory scientists). Participants should have
at least diploma qualification or second year level achievement
in life science undergraduate degree.
Aims
To
provide greater understanding of the concepts of modern
Immunology. You will gain:
1) Comprehensive knowledge of the immune physiology
(the cells and soluble mediators, and their interactions
in lymphoid and non-lymphoid tissues) in response
to antigens
2) Knowledge
about how the immune system, on one hand, is protective
against infection and malignancy but, on the other,
contributes to the pathology of allergies, autoimmunity
and transplant destruction.
3) The skills necessary for a career in biomedical
science
4) The
unit will be lecture based, with reference to the
current literature
