There was minimal perivascular inflammation in the specimens examined, but there was no vascular occlusion, as previously described in the Journal.1 Perivascular-activated microglia, macrophage infiltrates, and hypertrophic astrocytes were seen in 13 patients (Figure 1G and 1H, Fig. S3, and Table S4).2 There were CD3+ and CD8+ T cells in the perivascular spaces and in lumens adjacent to endothelial cells in 8 patients, which may have contributed to vascular injury (Figure 1I and 1J), as suggested in a previous report.3 Activated microglia were found adjacent to neurons in 5 patients, which is suggestive of neuronophagia in the olfactory bulb, substantia nigra, dorsal motor nucleus of the vagal nerve, and the pre-Bötzinger complex in the medulla, which is involved in the generation of spontaneous rhythmic breathing (Figure 1K through 1N and Fig. S3). |
