As President Trump claims that he is immune to COVID-19 and isolated reports emerge of reinfection, what is the truth about immunity to COVID-19? To date, there have been six published cases of COVID-19 reinfection, with various other unverified accounts from around the world. Although this is a comparably small fraction of the millions of people known to have been infected, should we be…
Innate immunity is the fastest-acting component of the immune system, but so far little is known about its role during infection with SARS-CoV-2. A few hours after an infection, the body emits an alarm signal, interferon, enabling cells that have not yet been infected to produce antiviral proteins. This phenomenon occurs well before the production of neutralizing antibodies. Scientists from the…

Harvey J. Alter, Michael Houghton and Charles M. Rice made seminal discoveries that led to the identification of a novel virus, Hepatitis C virus.
Our immune system can efficiently fend off viral diseases. Two types of immune cells play an important role in this process: The T-cells, which firstly can directly destroy virus-infected cells and secondly enable the formation of efficient, virus-neutralizing antibodies by B-cells. These two cell types also play a crucial role in the immune defense against SARS-CoV-2 infection. Whereas antibody…
The COVID-19 pandemic has created a flood of potentially substandard research amid the rush to publish, with a string of papers retracted or under a cloud and a surge in submissions to pre-print servers where fewer quality checks are made, a leading ethicist has warned in the Journal of Medical Ethics. This has implications for patients, clinicians, and potentially government policy, says…
As COVID-19 infections begin to rise again, a novel testing strategy proposed by researchers at the University of Oxford at the start of the pandemic has become urgent once again.

Researchers have developed a human cell ‘membrane on a chip’ that allows continuous monitoring of how drugs and infectious agents interact with our cells, and may soon be used to test potential drug candidates for COVID-19. The researchers, from the University of Cambridge, Cornell University and Stanford University, say their device could mimic any cell type - bacterial, human or even the…
New research from Karolinska Institutet and Karolinska University Hospital shows that many people with mild or asymptomatic COVID-19 demonstrate so-called T-cell-mediated immunity to the new coronavirus, even if they have not tested positively for antibodies. According to the researchers, this means that public immunity is probably higher than antibody tests suggest. The article is freely…
Major weaknesses exist in the evidence base for COVID-19 antibody tests, finds a review of the latest research published by The BMJ. The evidence is particularly weak for point-of-care tests (performed directly with a patient, outside of a laboratory) and does not support their continued use, say the researchers. Serological tests to detect antibodies against COVID-19 could improve diagnosis and…

Biomedical researchers in Munich have isolated immune cells from human tonsils obtained following routine surgery, and used them to analyze aspects of the immune response and test the effects of anti-inflammatory agents at the cellular level. Human tissues that have been surgically removed from patients are normally treated as waste, especially when they are derived from a ‘dispensable’ organ…
T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases – unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system…

For almost any conceivable protein, corresponding antibodies can be developed to block it from binding or changing shape, which ultimately prevents it from carrying out its normal function. As such, scientists have looked to antibodies as a way of shutting down proteins inside cells for decades, but there is still no consistent way to get them past the cell membrane in meaningful numbers. Now,…
Measles infections are not harmless – they can cause disease courses that may be of fatal outcome. Researchers of the Paul-Ehrlich-Institut (PEI) in co-operation with researchers from the UK and the Netherlands have now found out that measles viruses erase part of the immunological memory over several years. Affected persons are thus more susceptible to infections with other pathogens beyond…
Breast cancer could be detected up to five years before there are any clinical signs of it, using a blood test that identifies the body’s immune response to substances produced by tumour cells, according to new research presented at the 2019 NCRI Cancer Conference. Cancer cells produce proteins called antigens that trigger the body to make antibodies against them – autoantibodies. Researchers…
Advances in antiretroviral therapy mean that today, people infected with the human immunodeficiency virus (HIV) can expect a healthy and long life. However, living with HIV does increase the risk of cancer. The reasons for this are multiple and include behavioural risk factors (smoking etc.) but many cancers can be attributed to the effects the virus has on the immune system, specifically its…
Researchers at the University of Exeter first identified a gene in the 'hospital bug' Clostridioides difficile responsible for producing a protein that aids in binding the bacteria to the gut of its victims. In collaboration with researchers at Paris-SUD University, they then showed that mice vaccinated with this protein generated specific antibodies to the protein – and that C. diff that did…

Immuno-oncology is a therapy in which the body’s immune system treats a tumour. Dr Eric Borges, from the Research and Development Centre at Boehringer Ingelheim Pharma GmbH in Germany, explains why this is revolutionary. Unlike conventional cancer therapies, with immuno-oncology the tumour cell is not the direct target, it’s the patient’s immune system. The medication stimulates this to…
With a case fatality rate of 35 percent, a Middle East respiratory syndrome-related coronavirus (MERS-CoV) infection – also called camel flu – is a dangerous disease. About seven years ago, when the virus was first isolated, mortality was close to 100 percent since only severe infections that led to the patient being in intensive care were recorded. Today the environment of each victim is…

For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…
When immune cells invade the tumor, this is usually considered a good sign because the body's own immune system appears to be responding to the cancer. In the case of certain types of breast cancer immune cells, namely so-called tumor-infiltrating lymphocytes (TILs), these can determine survival rates and predict the usefulness of chemotherapy. This was shown by the largest meta study on TIL…
