Seminar Title:The role of IL-27 in limiting infection-induced
inflammation
(Language: English)
Summary:
T cells contribute to the control of many infections but can also
contribute to immune-pathology associated with certain chronic
diseases. Consequently&s_comma; there are numerous regulatory networks that
limit the pathological response and early studies identified IL-10 as
a key cytokine to prevent immune hyper-reactivity. More recently&s_comma; the
heterodimeric cytokine IL-27 has been shown to limit T cell responses
(Th1 and Th17) during toxoplasmosis and to inhibit multiple T helper
cell responses during other parasitic infections. Some of these
effects are through direct inhibition of T cell responses&s_comma; but IL-27
can also induce the production of IL-10. Moreover&s_comma; our preliminary
data indicate that different components of IL-27 have unique
biological functions and this has raised questions about the role of
the cytokine sub-units in promoting protective anti-parasite
responses versus limiting infection-induced pathology and controlling
Treg populations.
