Project description

Our laboratory has for the first time identified a new NOD-like receptor (NLR) protein in the regulation of inflammation in response to chronic Helicobacter pylori infection. Specifically, we have shown that conditional knockout mice lacking this NLR exhibit an accelerated formation of gastric B cell mucosa-associated lymphoid tissue (MALT), consistent with the early stages of MALT lymphoma, in response to chronic Helicobacter infection. The overall aims of the project are to investigate how this novel NLR prevents B cell lymphomagenesis induced by chronic infection and whether this protein may play much broader functions in the host immune system. These questions will be addressed in both in vitro and in vivo models, including conditional knockout mice. The project will involve various techniques, such as primary cell culture, mouse infection, immunohistochemistry, flow cytometry, cytokine ELISA and qPCR.
