Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Scurfy Mice Develop Features of Connective Tissue Disease Overlap Syndrome and Mixed Connective Tissue Disease in the Absence of Regulatory T Cells
Discussion Treg represent a lineage of T cells which play a fundamental role in maintaining humoral tolerance in the periphery. This subset of “suppressor T cells” is identified as FoxP3-expressing CD4+ T cells (16, 17). The unrestrained expression of FoxP3 is essential for the development and function of Treg (4). Accordingly, a disruption of the Foxp3 gene in scurfy mice results in an autoimmune lymphoproliferative disorder with fatal multi-organ inflammation (18). Since the causative mutation occurs in orthologous genes, the scurfy phenotype is indicated as the murine equivalent of the human IPEX sy...

Association of Fibrosing Myopathy in Systemic Sclerosis and Higher Mortality
ConclusionFibrosing myopathy is a unique histologic subtype of muscle disease among weak patients with SSc and is associated with significantly worse mortality compared to those with inflammation and/or necrosis on muscle biopsy.

Pulmonary Pathologic Manifestations of Anti-Alanyl-tRNA Synthetase (Anti-PL-12)-Related Inflammatory Myopathy.
CONCLUSIONS: - Lung disease is often the first manifestation of anti-PL-12 ARS. There are no pathognomonic histopathologic features to distinguish anti-PL-12 ARS-related lung disease from idiopathic variants of diffuse interstitial lung disease. Increased inflammation, lymphoid aggregates, and nonspecific interstitial pneumonia-like areas in a biopsy, as well as clinical features of mechanic's hands, Raynaud phenomenon, arthritis, and fever, should prompt pathologists to suggest involvement by ARS.

RIG-I expression in perifascicular myofibers is a reliable biomarker of dermatomyositis
Dermatomyositis (DM) is inflammatory myopathy or myositis characterized by muscle weakness and skin manifestations. In the differential diagnosis of DM the evaluation of the muscle biopsy is of importance amon...

Focal and Patchy Perifasicular Involvement Differentiates the Anti-Jo1 Inflammatory Myopathy (IM) from Dermatomyositis (DM) (P3.125)
Conclusions: Perimysial fragmentation and necrotizing perifascicular myositis are features that have been described by others to differentiate anti-jo1 IM form DM. In addition we found that the changes in muscle biopsies of patients with Jo1-IM are focal and patchy (affect some fibers, where others are spared at the same level) and tend to affect the most superficial layers of the fascicles. Muscle fiber necrosis and regeneration is seen in acute stages, while muscle fiber atrophy develop later in the course of the disease. This pattern of perifascicular involvement can help differentiate anti-jo1 IM from DM. Disclosure: D...

Pulmonary pathologic manifestations of anti-glycyl-tRNA synthetase (anti-EJ)-related inflammatory myopathy
Conclusions Identifying ARS-associated autoantibodies in ILD patients with or without myopathy is desirable because patients may respond well to immunosuppressive therapy, and their prognosis is better than that of patients with idiopathic forms of DAD or UIP.
