By this time point, extensive inflammatory cell infiltration could also be observed, dominated by mononuclear and polymorphonuclear cells 49.
Pathological tests revealed extensive inflammatory cell infiltration and caseous-like necrosis consisting of chronic granulomatous inflammation with acute necrotizing inflammation.
Virally-infected murine fibrotic lungs further displayed evidence of extensive inflammatory cell infiltration and increased levels of CCL2, TNFα, IL-1β and IL-10.
In contrast, this inhibitor was highly effective in attenuating extensive inflammatory cell infiltration associated with concomitant viral infection and it enhanced the antiviral cytokine response.
Joint grading was as follows [ 19]: normal, mild (minimum inflammatory cell infiltration and synovial hyperplasia with some cartilage loss), moderate (more extensive inflammatory cell infiltration and synovial hyperplasia with considerable bone erosion) and severe (complete destruction of joint architecture).
In contrast, NAC-treated mice demonstrated 10% necrotic hepatocytes and extensive inflammatory cell infiltration (250 ± 35 per high power field, n = 6) in the centrilobular region; however, no evident regeneration was seen.
The injected animals developed a disease that exhibited the following hallmarks of human BP: (a) clinical skin lesions; (b) in vivo deposition of rabbit IgG and mouse C3 at the basement membrane by direct IF; (c) dermal-epidermal separation and an extensive inflammatory cell infiltration by H&E staining [ 30].
Like other fatal HEV71 cases reported elsewhere (7, 16, 20, 21 ), the primary pathologic changes found at autopsy of four case-patients in this study were in the brain, including the brainstem, which showed extensive inflammatory cell infiltrate and focal necrosis.
At euthanasia, both IL-25−/− and WT mice treated with DSS had a similar shortening of colon length, and microscopic examination showed complete loss of crypts as well as extensive inflammatory cell infiltration in the muscularis mucosa, submucosa, and muscularis externa.
In conclusion, radiation exposure alone, which triggers intense inflammation and extensive recruitment of inflammatory cells, proved sufficient to prevent re-epithelialization of skin at 30 days.
