SEMA4A and myasthenia gravis: However, no significant correlation was found between the disease stage and semaphorin levels.<h4>Conclusion</h4>Our findings suggest that the levels of semaphorin 4A and 7A may not only support the diagnosis of MG and aid in differential diagnosis but also shed light on the development of future therapeutic protocols targeting semaphorin proteins and receptors in other autoimmune and inflammatory diseases.
