Muscle-specific kinase myasthenia gravis (MuSK-MG) is an autoimmune disorder caused by antibodies targeting the muscle-specific kinase (MuSK), causing muscle weakness. Although neurological autoimmunity can potentially increase the risk of cancer, not much is known about cancer rates among patients with MuSK-MG.
In this study, researchers explored the frequency and timing of cancer in patients with MuSK-MG. The team reviewed records of 94 patients, recording information about diagnosis and treatment of associated cancers. In two patients with MuSK-MG onset after cancer diagnosis, researchers performed immunohistochemistry to assess MuSK expression in cancer cells of tumor specimens.
Assessment of tumor specimens revealed strong nuclear expression of the MuSK protein in cancer cells. These findings suggest a new pathway in the formation of tumors as well as a potential therapeutic target. Authors note that this preliminary study needs to be replicated in a much larger cohort of patients to determine if cancers could be a trigger for MuSK MG.

Myasthenia gravis (MG) is a rare neuromuscular disorder that occurs when the body’s immune system attacks the nerve-muscle communication point, causing disabling weakness. Over the past few decades, understanding of MG has progressed significantly, leading to the development of new therapies.
In this review paper, researchers discuss the current understanding of pathophysiology and new therapies in MG. The team covers the various subgroups of MG as well as emerging therapeutic strategies. Authors note that these insights shed light on the evolving landscape of MG treatment and exciting prospects for further research.

Autoimmune diseases are a group of conditions caused by a dysregulated immune system that attacks and damages the body. As autoimmune diseases have become increasingly more common, new therapies have emerged. However, how they specifically alter the immune system is not well understood.
In this study, researchers studied the circulating autoantibody repertoire to further understand the effect of therapies used for autoimmune diseases. Leveraging a custom set of over 730,000 human-derived peptides (short chains of amino acids), the team explored variations in autoantibody profiles across individuals who were treated with different immune-modulating therapies.
Results show that each individual—regardless of disease state—has a distinct and complex set of autoantibodies, which creates a unique immunological footprint researchers call the “autoreactome” that remains surprisingly stable over many years. The team found that therapies targeting B cell maturation antigen (BCMA) greatly altered an individual’s autoreactome, while anti-CD19 and anti-CD20 therapies, which deplete B cells, had minimal effects. Authors note that these findings suggest the potential for BCMA therapy in treating autoantibody diseases that are resistant to current therapies.

Neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein Ab disease, and autoimmune myasthenia gravis (MG) are autoantibody-mediated autoimmune diseases. Autoantibodies can cause a type of immune reaction called Ab-dependent cellular cytotoxicity (ADCC) involving natural killer (NK) cells. However, it is not known whether ADCC contributes to disease development in patients with these conditions.
In this study, researchers investigated the characteristics of circulating NK cells in patients with NMOSD, myelin oligodendrocyte glycoprotein Ab disease, and MG. The team used functional assays, phenotyping, and transcriptomics to explore the role of NK cells in these diseases.
Results show elevated subsets of NK cells in patients with NMOSD and MG. Authors note that this elevation suggests prior ADCC activity occurring in the affected tissues.

Myasthenia gravis (MG) is a rare neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors (AChRs) or muscle-specific kinase (MuSK) on muscles. To date, the standard therapy for MG has relied on acetylcholinesterase inhibitors, corticosteroids, and immunosuppressants. These therapies have shown good efficacy in improving MG-related symptoms in most individuals. However, they can also cause long-term adverse effects, and up to 15% of individuals with MG show limited or no response.
This review paper provides a comprehensive overview of emerging molecular therapies for MG. The author discusses progress in therapies associated with AChR antibodies and MuSK antibodies, including both challenges and opportunities.
The author notes that molecular therapies have the potential to revolutionize the MG treatment landscape, unlocking new potential for personalized medicine approaches.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors (AChRs) in muscles. Double seronegative myasthenia gravis (dSN-MG) is a type of MG where patients do not have detectable AChRs or muscle-specific tyrosine kinase (MuSK) antibodies, which are two of the most common antibody markers for MG. In some patients with dSN-MG, a technique called cell-based assay (CBA) can be used to detect these antibodies. However, research comparing fixed and live CBA is lacking.
In this study, the research group of MGNet Pilot Awardee Valentina Damato, MD, PhD, compared the performance of fixed and live CBAs in serum samples from 192 patients with radioimmunoassay (RIA)-dSN-MG and 100 control subjects. The team also assessed the sensitivity and specificity of these techniques in RIA-positive MG samples.
Results show that fixed CBA represents a valuable alternative to RIA for AChR and MuSK antibody detection in patients with MG. Authors note that fixed CBA could be considered as a first-step diagnostic test, while live CBA can be useful in serologic testing of RIA- and fixed CBA-negative samples.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles. The primary initial therapy for MG is high-dose prednisone use. However, more than a third of patients do not respond to this treatment. Currently, there are no biomarkers to predict clinical responsiveness to corticosteroid treatment.
In this study, researchers defined a treatment-responsive biomarker for MG patients undergoing corticosteroid therapy. The team used serum from MG patients collected for a clinical trial of thymectomy (removal of the thymus gland) and prednisone to create metabolomic and lipidomic profiles. Next, researchers correlated these profiles with treatment response.
Results show that metabolomic and lipidomic profiles could be used to predict treatment response. Authors note that variation in prednisone metabolism may determine how well patients respond to treatment.

Myasthenia gravis (MG) is a rare neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors (AChRs) on muscles. High-dose chemotherapy (HDIT) and autologous hematopoietic cell transplantation (HCT), also known as bone marrow transplant, are potential treatments for MG.
In this study, researchers investigated the safety and efficacy of HDIT and HCT in a patient with severe, treatment-resistant MG. Results show that HDIT and HCT induced remission of MG. The team also assessed the effect of treatment on the underlying immunopathology. Intriguingly, the AChR autoantibodies—the known pathogenic mediators of MG—did not appreciably lower after the treatment.
Authors state that these findings suggest a cell-based disease mechanism, which responds to high-dose therapy, may play a role in the pathology in addition to AChR autoantibodies. Further studies are needed to establish whether HDIT and HCT can be an effective therapy for severe MG.

Myasthenia gravis (MG) is a neuromuscular disorder which produces muscle weakness that can worsen over the course of a minute during an examination. Use of telemedicine has recently increased for monitoring MG, although these evaluations rely entirely on subjective evaluations of an examiner.
In this study, researchers developed a new telehealth platform to assist with telemedicine evaluations of ocular manifestations of patients with MG. The team created a hybrid algorithm that combines deep learning with computer vision, giving quantitative metrics of ptosis (eyelid droop) and ocular muscle fatigue leading to symptoms like double vision.
The method, which works on both a fixed image and frame by frame of the video in real-time, is able to operate in standard telehealth conditions. Authors note that this approach is general and can be applied to many disorders of ocular motility and ptosis.

In patients with myasthenia gravis (MG), an autoimmune response blocks or damages acetylcholine receptors in muscles. Autoantibody clones drive three different pathogenic (disease-causing) mechanisms of MG, including complement activation, receptor blockade, and antigenic modulation. However, it is unclear whether these mechanisms are driven by single or multiple antibody clones.
In this study, researchers investigated the ability of individual autoantibody clones to drive multiple pathogenic mechanisms of MG. First, the team produced monoclonal autoantibodies (mAbs) from patients with MG. Next, researchers assessed the binding properties and pathogenic capacities of the mAbs.
Results show that these mAbs can drive pathology through blocking the acetylcholine binding site, internalizing the AChR through crosslinking (modulation), and activating complement. While some mAbs can drive one or two of these mechanisms, several mAbs were able to drive all three simultaneously. Authors note that these new insights on the immunopathology of MG could help inform therapeutic approaches.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles. Recently, telemedicine practices have grown for neurological diseases, including MG. Telemedicine evaluation of patients with MG has been recommended via the Myasthenia Gravis Core Examination (MG-CE).
In this study, researchers developed a new telehealth system to automate data acquisition and analytics during the MG-CE. Using Zoom videos of patients with MG undergoing the MG-CE, the team created an algorithm toolbox—including computer vision and signal processing methods—to analyze eye motions, body motions, and vocalizations.
Results show that this new system can objectively quantitate metrics from the MG-CE, allowing the medical examiner to concentrate on the patient instead of managing logistics. Authors note that the system could also be applied to many other neurological disorders, potentially improving clinical care.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles. Affected receptors cannot properly receive nerve signals, impacting voluntary muscle contractions. Generalized muscle weakness and fatigue with prolonged activity are characteristic symptoms, which improve with rest. In this review article, authors summarize recent insights into the development of MG relating to the immune system, including the mechanisms of various MG disease subtypes. They also describe the wide range of treatment options now available to patients with MG, which have uncovered significant differences in clinical responses between subtypes. These differences could help clinicians choose specific therapeutic strategies. Authors conclude that improved understanding of autoantibodies is revealing the mechanisms that guide the development of MG. In the future, authors note that studies on the differences in immunology among MG patients will be key to developing effective, individualized therapies.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles. Clinical assays—laboratory tests used to diagnose and monitor patients—only measure autoantibody binding. Therefore, these tests often provide limited insight on disease burden and therapeutic response. To address these limitations, Dr. Kevin C. O’Connor and colleagues at Yale University developed a new assay for evaluating acetylcholine receptor autoantibody–mediated complement activity. Results suggested that a subset of patients lacks association between membrane attack complex formation and autoantibody binding or disease burden. Authors note that this assay provides a better understanding of autoantibody mechanisms and may improve predictions for treatment response. Ultimately, these measurements could help assess disease progression and provide more individualized treatment plans.
