CXCR5-negative natural killer cells ameliorate experimental autoimmune myasthenia gravis by suppressing follicular helper T cells

Recent studies have demonstrated that natural killer (NK) cells can modulate other immune components and are involved in the development or progression of several autoimmune diseases. However, the roles and me...

Conclusion: The combination of physician-evaluated and patient-reported outcome measures provided a more discerning picture of patient status and response to treatment. Incorporating MG outcome measures into clinical practice would aid in modulating therapies.

Myasthenia Gravis (MG) is an autoimmune disease of the neuromuscular junction (NMJ), with autoantibodies binding proteins in the NMJ detected in ∼85% of the patients. However, 10-15% of MG patients present with no known antibodies [1,2]. Congenital myasthenic syndromes (CMS), in turn, are disorders of the NMJ due to various genetic defects in components essential for NMJ structure and function. Symptoms in CMS patients typically start shor tly after birth or during childhood, with an adult onset being rarer.

In conclusion, our study summarizes the regulatory transcription factors that drive expression of AChR+ and MuSK+ MG-associated miRNAs. Our findings of elevated miR-21-5p and miR-30e-5p expression in immune cells upon inflammatory stimulation and the suppressive effect of corticosteroids strengthens the putative role of these miRNAs in the MG autoimmune response.

Discussion Myasthenia gravis (MG) is a problem of the neuromuscular junction which causes muscle weakness. It can occur in all ages and have a range of symptoms from mild localized disease to mortality-threatening respiratory failure. MG occurs in 1.7-30 cases/million, with a prevalence of 77.7 cases/million. Pediatric patients comprise 10-15% of all patients with MG. In various Asian populations, the juvenile MG can be up to 50% of all of the MG cases. Fluctuations in muscle weakness is a hallmark of the disease. As a reminder, “[i]n normal synaptic transmission in the neuromuscular junction, the axon is depolarize...

CONCLUSIONS These results indicate that grilled nux vomica ameliorates EAMG by depressing the TLR-4/NF-kappaB signaling pathway, and hub genes may serve as potential targets for MG treatment. PMID: 32052794 [PubMed - in process]

AbstractLambert ‐Eaton myasthenic syndrome (LEMS) is an autoimmune neuromuscular junction disease associated with P/Q‐type voltage‐gated calcium channels (P/Q‐type VGCCs) autoantibodies1. P/Q ‐type VGCCs present at the presynaptic motor nerve terminals and their antibodies induce a reduction in neurotransmitter release, leading to the characteristic muscle weakness associated with the disease. Approximately half of LEMS patients have small‐cell lung carcinoma (SCLC) that occurs as a paraneoplastic disorder.

Myasthenia gravis (MG) is an autoimmune disease characterized by muscle weakness and fatiguability of skeletal muscles. It is an antibody-mediated disease, caused by autoantibodies targeting neuromuscular junction proteins. In the majority of patients (~85%) antibodies against the muscle acetylcholine receptor (AChR) are detected, while in 6% antibodies against the muscle-specific kinase (MuSK) are detected. In ~10% of MG patients no autoantibodies can be found with the classical diagnostics for AChR and MuSK antibodies (seronegative MG, SN-MG), making the improvement of methods for the detection of known autoantibodies or...

Purpose of review Ocular myasthenia gravis (OMG) is a complex condition with heterogenous phenotypes and ill-defined diagnostic criteria. Understanding concomitant risk factors and autoimmune serology can help inform prognosis for generalization and guide treatment. Recent findings Although antibodies to acetylcholine receptors or muscle-specific kinase likely increase risk of generalization, they are less frequent in OMG. Patients without either antibody tend to have a milder disease process and often have variable antibodies to other end-plate proteins such as LRP4, agrin, or cortactin. The treatment of OMG begins w...

Extranodal marginal zone lymphoma of mucosa ‐associated lymphoid tissue (MALT) in the thymus is a rare disease. Furthermore, amyloid deposition in thymic MALT lymphoma has not been previously described. Here, we report a case of a 35‐year‐old man with thymic MALT lymphoma with amyloid deposition and myasthenia gravis. Chest computed tom ography revealed an anterior mediastinal mass with internal cystic component and extensive calcification. Total thymectomy was performed and histopathologic findings were compatible with a diffuse amyloid deposition in extranodal marginal zone MALT lymphoma. The results indicate that ...
