T-cells

A recent study published in Nature Communications showed, for the first time, that a protein complex called LUBAC is responsible for controlling the late-stage development of immune T-cells before they are released into the bloodstream. Several types of cells compose the immune system, working together to fight infections or cancer.

Changes in the composition of certain immune system cells may be associated with relapses in multiple sclerosis (MS) patients being treated with Gilenya (fingolimod), according to a study published in the journal Scientific Reports. The study, “Altered T Cell Phenotypes Associated With Clinical Relapse Of Multiple Sclerosis Patients Receiving…

Damaging immune system defects seen in patients with multiple sclerosis (MS) can be repaired using a simple stem cell approach, according to a new study by researchers in China and the U.S. The study, “Umbilical Cord-Derived Mesenchymal Stem Cells Reversed The Suppressive Deficiency Of T Regulatory Cells From Peripheral Blood Of…

The experimental therapy laquinimod was seen to prevent the start of harmful immune responses and to disrupt the progression of multiple sclerosis (MS) in a mouse model of the disease. This finding may be especially promising, as the treatment is being developed for people with both relapsing MS and its rarer progressive…

Antioxidant-filled nanoparticles injected under the skin may become a future multiple sclerosis (MS) treatment that comes with a perk or a drawback, depending on how a patient sees it.  The injection leaves a temporary dark spot on the skin, resembling a tattoo. The tattoo might be a small issue considering…

How the multiple sclerosis (MS) therapy Tecfidera (dimethyl fumarate) works on a molecular level has finally been uncovered, using a new method that can map a drug’s protein targets. The insights gained may open up new avenues for the development of more specific drugs, based on the same mechanisms, but with fewer side effects. The study,…

Scientists recently reported additional mechanisms of action that may underlie Gilenya (fingolimod) beneficial effects in relapsing-remitting multiple sclerosis (RRMS). The results were in an oral presentation, “Fingolimod therapy modulates B cell functions: reduces CXCR4-mediated migration and increases B cell -mediated anti-inflammatory cytokine profile,” given at the 32nd Congress of the European Committee for Treatment…

A mutation in a mouse model of the John Cunningham (JC) virus, which causes progressive multifocal leukoencephalopathy (PML), allows the virus to evade the host immune responses in people with multiple sclerosis (MS), according to a study into the mechanisms of PML. Infection with the JC virus most often passes unnoticed in healthy…

Opexa Therapeutics, Inc., announced that its president and chief executive officer, Neil K. Warma, recently gave a presentation on immunotherapy and its potential for treating autoimmune disorders, including multiple sclerosis, at the recent Cellular Horizons: The Third International Conference on the Progress of Regenerative Medicine and its Cultural Impact held at the Vatican. Neil…

Clinical trials have shown that ocrelizumab — an antibody targeting B-cells — is effective in multiple sclerosis (MS). As a result, some researchers and clinicians claim that B-cell depletion is a sufficient therapy in MS, and that drugs targeting other immune cells are obsolete. Not everyone agrees. A debate at…

Sanofi Genzyme, one of the companies participating in the four-day 10th World Congress on Controversies in Neurology (CONy) in Lisbon, Portugal, that concluded on March 20, 2016, supported several symposiums focused on multiple sclerosis (MS) — including one on B-cell and T-cell therapies. For over a decade, Sanofi Genzyme has worked to develop effective therapies…

In an innovative research project funded by the National Multiple Sclerosis Society, Dr. Anne Astier from the University of Edinburgh, U.K., and her team will use zebrafish to track the CD46 protein and determine where and how it affects the movement of immune cells into the brain, a process believed to influence…

Researchers have found that changes in the composition of immune molecules — specifically, a shift to more anti-inflammatory cytokines and regulatory T-cells (Tregs) — likely account for the efficiency of alemtuzumab (Lemtrada) as a treatment for relapsing-remitting multiple sclerosis (RRMS). The study, titled “Alemtuzumab long-term immunologic effect: Treg suppressor function…

Researchers have discovered a protein regulator that leads to autoimmune inflammation in multiple sclerosis (MS) patients, a possibly important discovery because potential therapeutic targets for diseases like MS are believed to lie in this cascade of inflammatory events. The researchers, in fact, suggest that the regulator, called Trabid, is one of…

Delayed-release dimethyl fumarate (Tecfidera) was recently approved for patients with relapsing-remitting multiple sclerosis (RRMS), although the mechanisms by which the drug exerts its action were not fully understood. A new study from the University Hospital Münster, Germany, shows that dimethyl fumarate alters the balance between subpopulations of T-cells to promote…

A team of researchers recently discovered two novel multiple sclerosis (MS)-associated genes that are regulated by vitamin D levels. The study, titled “The multiple sclerosis susceptibility genes TAGAP and IL2RA are regulated by vitamin D in CD4+ T cells,” was published in the advanced online section of …

Tiziana Life Sciences, plc, a biotechnology company specializing in drugs to treat immunological and oncological diseases,  recently announced its intent to further develop foralumab, a fully human monoclonal antibody targeting the CD3 receptor. This approach, aiming to modulate the immune T cell response and achieve immunosuppression, is well-validated and has the potential to…

In a new study entitled “Transcription factor Nr4a1 couples sympathetic and inflammatory cues in CNS-recruited macrophages to limit neuroinflammation,” a team of scientists discovered the mechanism by which autoreactive T cells are capable of penetrating a patient’s brain and induce multiple sclerosis. The study was recently published in the advance online issue…

Results from a recent study published in the journal Immunity indicate that dietary fat has an influence in the duration and severity of autoimmune flare-ups in a mouse model of multiple sclerosis. The team of researchers also showed that adjusting the length of the fatty acids consumed by…

Researchers from the Gladstone Institutes have shown in a new study that fibrinogen, an important blood coagulation protein, can induce an autoimmune response in the central nervous system when the blood-brain barrier (BBB) is disrupted and blood proteins enter the brain. The study, entitled “Blood coagulation protein fibrinogen promotes…

Melatonin, the same hormone that helps people fall asleep by regulating the body’s internal clock, may be helpful in treating multiple sclerosis, according to a study from Raúl Carrea Institute for Neurological Research in Buenos Aires. Neurologists Dr. Mauricio Farez and Dr. Francisco Quintana noticed that when melatonin levels are…
