SARS-CoV-2 has become a serious challenge for many areas of medicine, including neurology .In this sense, since the beginning of the pandemic, there has been a special concern for those people suffering from Multiple Sclerosis (MS), especially those who are being treated with disease-modifying therapies (DMTs) , since it is believed that these patients may be at higher risk of infection or . The immune response against antigens optionally coupled, fused or . Accumulating evidence has shown that antibody-independent B-cell functions, antigen presentation to T cells and the production of cytokines, are involved in the pathogenesis of CNS inflammatory diseases. B cells are major players in immune responses being the source of protective antibodies and antigen presenting cells. The current T cell maturation paradigm assumes that, in a healthy body, self-reactive T cells are deleted or inactivated in the thymus. This would be . When self-tolerance fails, auto reactive B cells produce autoantibodies and pro-inflammatory cytokines leading to the development of autoimmune diseases. This new understanding of the role of B cells opened up novel therapeutic options for the treatment of autoimmune diseases. However, B cells also have other functions beyond antibody production. Many recent studies have ass In the past 15 years, B cells have been rediscovered to be not merely bystanders but rather active participants in autoimmune aetiology. The invention relates to the finding that virus like particles (VLPs) can be loaded with immunostimulatory substances, in particular with DNA oligonucleotides containing non-methylated C and G (CpGs). During the last decade, it has become increasingly apparent that B lymphocytes not only produce autoantibodies but also exert important regulatory roles independent of their function as antibody-producing cells. CD22 mediates the effects of Gal9 to promote immunotherapy for allergic diseases by inducing B10 cells. B cells play a complex role in the development of systemic autoimmune diseases, especially in primary Sjgren's syndrome, a progressive condition that damages saliva and tear glands and leads to dry mouth, dry eyes, and other symptoms.
