Lymphatic vessel contractile activity and intestinal inflammation|
Theresa F Wu; Wallace K MacNaughton & Pierre-Yves von der Weid
Edema is a consistent observation in inflamatory bowel disease (IBD), and immune responses are inevitable in inflammation. Because the lymphatic system is an integral part of both tissue fluid homeostasis and immune reactions, it is likely that lymphatics play a role in the complex etiology of IBD. Despite the consistent findings that the lymphatic system is altered during gastrointestinal inflammation, the majority of studies conducted on the disease only mention the lymphatic system in passing. The effects of inflammatory mediators on lymphatic vessel function also remain poorly defined, despite its essential role in immunity and prevention of tissue edema. Processes allowing effective lymph transport are altered during inflammation, however, the mode of alteration and reason why lymphatics are ineffective in inflammatory reactions need to be further investigated. In addition, these processes have not yet been examined in an appropriate animal model and little has been done using in vivo methods of investigation in any model of gastrointestinal inflammation. This paper reviews the role of the lymphatic system in intestinal inflammation, as well as the role of the inflammatory products in mediating lymphatic contractile function.
