From the British and Spanish Societies for Immunology BiteSized Immunology BiteSized Immunology is a developing online resource designed to form a comprehensive guide to the immune system, yet approaching the topic via punchy, easy-to-digest, entries that outline major learning points. You...

‘It’s all gone’: CAR-T therapy forces autoimmune diseases into remission https://www.nature.com/articles/d41586-023-03968-6 Engineered immune cells have given 15 people with once-debilitating autoimmune disorders a new lease on life, free from fresh symptoms or treatments. The results raise...

Immunological profiling in long COVID: overall low grade inflammation and T-lymphocyte senescence and increased monocyte activation correlating with increasing fatigue severity Background: Many patients with SARS-CoV-2 infection develop long COVID with fatigue as one of the most disabling...

SARS-CoV-2-specific T cell therapy for severe COVID-19: a randomized phase 1/2 trial Abstract Despite advances, few therapeutics have shown efficacy in severe coronavirus disease 2019 (COVID-19). In a different context, virus-specific T cells have proven safe and effective. We conducted a...

The incidence of human herpesvirus (HHVs) is gradually increasing and has affected a wide range of population. HHVs can result in serious consequences such as tumors, neonatal malformations, sexually transmitted diseases, as well as pose an immense threat to the human health. The cGAS-STING...

Abstract: Millions globally suffer from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The inflammatory symptoms, illness onset, recorded outbreak events, and physiological variations provide strong indications that ME/CFS, at least sometimes, has an infectious origin, possibly...

Microglia Transcriptional Profiling in Major Depressive Disorder Shows Inhibition of Cortical Gray Matter Microglia https://www.biologicalpsychiatryjournal.com/article/S0006-3223(23)01239-8/fulltext Biological psychiatry Microglia have been implicated in the pathophysiology of major depressive...

Abstract Viral infection in most people results in a transient immune/inflammatory response resulting in elimination of the virus and recovery where the immune system returns to that of the pre-infectious state. In susceptible people by contrast there is a transition from an acute immune...

The immunology of long COVID Abstract Long COVID is the patient-coined term for the disease entity whereby persistent symptoms ensue in a significant proportion of those who have had COVID-19, whether asymptomatic, mild or severe. Estimated numbers vary but the assumption is that, of all...

Higher immune-related gene expression in major depression is independent of CRP levels: results from the BIODEP study https://www.nature.com/articles/s41398-023-02438-x Abstract (paragraphs mine) Compelling evidence demonstrates that some individuals suffering from major depressive disorder...

Introduction: Many people with long COVID symptoms suffer from debilitating neurologic post-acute sequelae of SARS-CoV-2 infection (Neuro-PASC). Although symptoms of Neuro-PASC are widely documented, it is still unclear whether PASC symptoms impact virus-specific immune responses. Therefore, we...

Tissue injury and leukocyte changes in post-acute sequelae of SARS-CoV-2: review of 2833 post-acute patient outcomes per immune dysregulation and microbial translocation in long COVID Abstract A significant number of persons with coronavirus disease 2019 (COVID-19) experience persistent...

Abstract Previous studies have shown that monocytes can be ‘trained’ or tolerized by certain stimuli to respond stronger or weaker to a secondary stimulation. Rewiring of glucose metabolism was found to be important in inducing this phenotype. As we previously found that Borrelia burgdorferi...

https://www.nature.com/articles/s41586-022-05105-1 Abstract CD8+ T cells that respond to chronic viral infections or cancer are characterized by the expression of inhibitory receptors such as programmed cell death protein 1 (PD-1) and by the impaired production of cytokines. This state of...

Recovering or Persisting: The Immunopathological Features of SARS-CoV-2 Infection in Children Buonsenso D, Valentini P, De Rose C, Tredicine M, Pereyra Boza MdC, Camponeschi C, Morello R, Zampino G, Brooks AES, Rende M, Ria F, Sanguinetti M, Delogu G, Sali M, Di Sante G, on behalf of the...

Full title: Unexplained post-acute infection syndromes Authors: Jan Choutka, Viraj Jansari, Mady Hornig & Akiko Iwasaki Published: Nature, 18 May 2022 Abstract SARS-CoV-2 is not unique in its ability to cause post-acute sequelae; certain acute infections have long been associated with an...

In an exploratory trial treating “long COVID” with the CCR5-binding antibody leronlimab, we observed significantly increased blood cell surface CCR5 in treated symptomatic responders but not in nonresponders or placebo-treated participants. These findings suggest an unexpected mechanism of...

Full title: How mycobacterium tuberculosis infection could lead to the increasing risks of chronic fatigue syndrome and the potential immunological effects: a population-based retrospective cohort study Abstract Background Chronic fatigue syndrome (CFS) has been shown to be associated with...

Preprint https://www.researchsquare.com/article/rs-1344323/v1 Post-acute sequelae of COVID (PASC), or long COVID, is a multisystem complication of SARS-CoV-2 infection that continues to debilitate millions worldwide thus highlighting the public health importance of identifying effective...

:emoji_warning: At this point it's still a preprint. Abstract: As most of you know, in the 80s researchers were excited about several (and separate) finds of retroviral activity in what we now call ME/CFS patients. The main researcher was Elaine DeFreitas, whose finds got dismissed by UK...
