Just a few days ago, the Cambridge team led by Ravindra Gupta announced that they had been able to eliminate HIV virus in a patient that had received a bone marrow transplant from a donor that carried two mutated copies of CCR5 -a mutation that occurs in around 1% of european descent- that confers HIV immunity to the host. The treated patient stopped taking antiretroviral drugs in the past 18 months after the transplant and, quite importantly, represents the second case of succesful HIV-treating transplant in recent years, the first having been reported in 2009. Interestingly, the idea behind a stem cell-based treatment came, for both patients, from the necessity of a bone marrow transplant as a treatment for a blood cancer that did not respond to chemotherapy; however, rather than chosing any compatible donor, Dr. Gupta opted for a patient with a double mutation for CCR5.

"Our most popular course covers the major topics in cellular and molecular immunology, including innate immunity, B cells, T cells, dendritic cells, cytokines and mucosal immunity. Other lectures cover autoimmune, allergic and immunodeficiency diseases, as well as new advances in interventional and clinical immunology and the molecular and genetic basis of immunologically-mediated diseases. All lecturers encourage interaction with the students through questions and discussions during lecture time. There is also ample opportunity for students to interact with the faculty outside the lecture room."

 

Experimental autoimmune encephalomyelitis (EAE) is quite possibly the most widely used animal model for multiple sclerosis (MS) and has shed light on several immunopathogenic processes that lead to this disease. On the other hand, grey matter degeneration -a crucial hallmark of the human MS- has always represented an elusive element in this model as EAE mice do not present grey matter damage, mostly due to the fact that the induction of the pathology is obtained mostly by triggering an immune reaction against myelin. Considering the emerging importance of this kind of lesion in MS, Dmitri Lodygin and colleagues sought to define a pathophisiologic process that underlied grey matter lesion.

Aryl hydrocarbon receptor (AHR) is a pivotal protein that belongs to PAS [PER (periodic circadian protein)-ARNT(AHR nuclear translocator)-SIM (single-minded protein)] domain-containing receptor superfamily. This group of proteins play a central role in regulating cellular homeostasis by sensing endogenous (e.g. redox status and oxygen partial pressure) and exogenous stimuli (e.g. toxic aromatic hydrocarbons), and AHR, in particular, is recently emerging as an important gear of the machinery that regulates inflammation in the gut-brain axis (see here). The endogenous ligands for AHR include, mostly, triptophan derivatives which are either produced by endogenous metabolic pathways or by the commensal microbiota, which -on the other hand- can also produce other distinct molecules that possess AHR agonistic activity and are involved in a series of immunoregolatory functions (e.g. they can limit intestinal inflammation). 

 

The dire situation that UK scientific community has been fearing in these last two years is, quite probably, one of the consequences that people voting for brexit in 2016 failed to consider. Brexit, and in particular the catastrophic perspective of a no-deal exit from the EU - which last 15 january became more likely as the UK parliament fiercely rejected the last negotiations - would not only leave UK science without arrangements on european fundings (e.g. H2020), but would also have more direct consequences until new immigration rules are properly discussed (40% of the scientific workforce comes from other EU nations, as stated by Paul Nurse, director of the Francis Crick Institute in London). With this scenario in mind, UK scientists are starting to elaborate possible contingency plans in the event of a hard brexit.

B cells are involved in the pathogenesis of multiple sclerosis (MS) and, as a matter of fact, many drugs are designed to target CD20+ B cells as a treatment for this disease. However, many surprising evidences still suggest, to date, that our knowledge concerning the role of B cell axis in MS is still quite incomplete: for example, drugs targetting the plasma cells (PC) (the antibody-producing mature form of B cells) survival niches unexpectedly result in exacerbation of the disease. In light of these, more the involvement of antibody-secreting cells in immunomodulation during MS needs to be fully assessed. Interestingly, recent evidences show that IgA-producing PC possess antiinflammatory properties; plasma cells directed against tissue-specific antigens can be found way far from their mucosal origin and can be enriched in different organs, including the brain of MS patients. In light of this, Olga L. Rojas, Anne Katrin Probstel and Elisa A. Porfilio, as well as their many colleagues, sought to investigate a possible immunoregulatory role for  IgA-producing cells in multiple sclerosis.
