Abstract

The immune system is integrated into the circuitry of every organ of the body, where it not only protects from infection, but helps to repair damaged tissue, removes cancer cells, helps to regulate metabolism, and serves as a conduit for communicating information throughout the body into all parts of our physiology. However, the immune system also has enormous capacity to wreak havoc on host tissues and organ function, if inappropriate or misdirected immune responses occur. Many of the maladies affecting humans today have an underlying immune component resulting from incorrect immune targeting associated with insufficient immune regulation. These include autoimmune diseases, allergies and infection-associated inflammatory damage (e.g. cytokine storm).

Nearly 90% of all immune cells in the body are associated with the gastrointestinal tract and these immune cells are continuously exposed to a wide range of microbes and microbial-derived compounds. Potent tolerance mechanisms ensure that these immune cells do not over-react, but instead they respond to infectious challenges in an robust, effective and well controlled manner. Recent changes in dietary habits and microbiota composition, especially evident in obese individuals, have resulted in reduced levels of immune regulatory metabolites that are expected and evolutionarily hardwired into our immune cell decision making processes. The lack of immune regulatory molecules results in a hypersensitive immune system that does not respond effectively to infection but is associated with a chronic state of inflammation that culminates in organ damage and disease for an increasing number of people.

ABOUT THE LECTURE & WORKSHOP SERIES – INFECTION & IMMUNITY

The LIH Lecture Series and Workshops in Infection and Immunity, supported by the FNR, are gathering internationally recognised speakers to address topics around Infection and Immunity. Lectures will be organised, followed by workshops especially dedicated to early-stage researchers.

Attendance to the lectures and workshops are free of charge. Should you be interested in registering for the workshops, please feel free to do so by sending us an email.


REGISTRATION

Registration is mandatory by sending an email to Florence Henry.
