When accompanied by peribronchiolar metaplasia, centrilobular fibrosis strongly suggests prior small airway injury, perhaps due to chronic HP, and a careful search for residual granulomas or giant cells should be undertaken.

Diagnostic Approach to Advanced Fibrotic Interstitial Lung Disease: Bringing Together Clinical, Radiologic, and Histologic Clues

As shown in Figure 4(b), asthma group mice showed prominent neutrophil infiltration of the peribronchiolar and perivascular connective tissues, together with the hypersecretion of mucus by epithelial cells.

Anti-HMGB1 neutralizing antibody ameliorates neutrophilic airway inflammation by suppressing dendritic cell-mediated TH17 polarization

We observed peribronchiolar inflammation 1 day after Cr(VI) exposure, which increased up to 8 days after intranasal treatment (Figure 1D).

Lung inflammation, injury, and proliferative response after repetitive particulate hexavalent chromium exposure

Histologically, the OP pattern is characterized by a temporally uniform proliferation of intra-alveolar organizing fibroblastic tissue in a patchy peribronchiolar distribution.

Not much is known about the role of macrophages in this part of the disease, but pigmented macrophages were found to cluster around small airways and these were associated with peribronchiolar fibrosis [81].

Macrophage heterogeneity in respiratory diseases

Mexico City dogs exhibit focal peribronchiolar inflammatory infiltrates that surround the adjacent blood vessels, some of which contain platelet thrombi and marginated neutrophils (CalderOin-Garciduenas et al.

Scores for peribronchiolar inflammatory cell infiltrates in sections from each lung were graded; a score of 0 indicated the absence of inflammatory cell infiltrates; a score of 1, less than five layers of inflammatory cells in <50% of the bronchiolar submucosa; 2, more than five layers of inflammatory cells in <50% of the bronchiolar submucosa; 3, less than five layers of inflammatory cells in >50% of the bronchiolar submucosa; and 4, more than five layers of inflammatory cells in >50% of the bronchiolar submucosa [18].

Cardiovascular effects of pulmonary exposure to single-wall carbon nanotubes

Detailed morphometric analysis has extensively expanded our knowledge of airway alterations in both membranous and respiratory bronchioles, (14) and it has documented airway narrowing with inflammation and fibrosis, and loss of the peribronchiolar alveolar attachments.

The Pathology of Chronic Obstructive Pulmonary Disease: Progress in the 20th and 21st Centuries

At 14 days after infection, we observed diffuse granulomatous pneumonia and the severe destruction of lung parenchyma with the peribronchiolar and perivascular infiltration of macrophages and neutrophils (Figure 5(h)).
