Steroid-Resistant Lymphatic Remodeling in Chronically Inflamed Mouse Airways

Abstract: Angiogenesis and lymphangiogenesis participate in many inflammatory diseases , and their reversal is thought to be beneficial. However , the extent of reversibility of vessel remodeling is poorly understood. We exploited the potent anti-inflammatory effects of the corticosteroid dexamethasone to test the preventability and reversibility of vessel remodeling in Mycoplasma pulmonis-infected mice using immunohistochemistry and quantitative RT-PCR. In this model robust immune responses drive rapid and sustained ch… Show more

“…For these conditions, treatment with anti-VEGF antibodies can, in some cases, promote disease resolution [106][107][108][109]. Furthermore, while vascular angiogenesis can be reversed in chronic inflammation, lymphangiogenic structures seem to persist [103,110]. This implies that while the blood vasculature requires both growth and maintenance cues the lymphatic vasculature may not.…”

“…The anti-inflammatory action of dexamethasone similarly reduces the load of M. pulmonis in the airways. 59 Both of these actions reflect the link between conditions that influence the growth of the organisms and the magnitude of the inflammatory response. They also fit with the reciprocal interdependence of the severity of M. pulmonis infection and magnitude of the inflammatory response.…”

“…There is evidence that newly synthesized corneal or tracheal lymphatic vessels do not regress and persist after the resolution of an inflammatory process. 2,5,6 In contrast, there are data to support that lymphatic vessel regression develops in the cornea after inflammation and that these vessels increase the risk of corneal transplant rejection. 7,8 However, the details of this process are largely unknown.…”

“…We identified lymphatic vessel fragments as a portion of the vessels comprising the relative density. Lymphatic vessel fragmentation is process that has been identified by others, 6 and does not seem to be a mechanism used by the blood vascular system. 13 We suspect that vessel fragmentation has some relationship to the regressed lymphatic vessel regions with decreased LYVE-1 expression and the button-like expression pattern of CD31, and VE-cadherin expression, a phenotype that was recognized by Baluk et al…”
