As the COVID-19 pandemic continues to claim lives around the world, much research has focused on the immune system’s role in patients who become seriously ill. A popular theory has it that the immune system gets so revved up fighting the virus that, after several days, it produces a so-called cytokine storm that results in potentially fatal organ damage, particularly to the lungs.
The SARS CoV-2 virus which causes COVID-19 may have been named prematurely. As more has become known about the infection, the severe disease does not appear to be a respiratory syndrome at all. Patients who only have a respiratory illness tend not to have a severe condition, while patients who develop a severe condition tend to have non-respiratory conditions, primarily thrombotic or hyper-immune…
There are major complications from COVID-19 – ARDS, pulmonary embolism and neurological – that imaging can help detect, manage and/or follow up in the long term, radiologists from France and the UK explained during a recent ESR Connect session.

Chimeric Antigen Receptor (CAR)-T cell therapy, for instance, is a…
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…
In breast cancer, one of the most common cancers in women, tumors contain a small amount of so-called cancer stem-like cells (CSCs). Being able to eliminate breast-cancer stem-like cells in a targeted way is essential for developing successful therapies — conventional treatments, such as chemotherapy or radiotherapy followed by drug intake, do not target CSCs. A better understanding of the…
While the role of the laboratory in disease diagnosis and management has expanded in recent years, causing an overwhelming rise in testing demands, the availability of skilled technologists and specialists has been diminishing. To meet the needs of an overworked and increasingly generalized workforce, today’s products not only must deliver more clinical data than ever before, but also must be…
Australia's national science agency CSIRO has identified a new gene that plays a critical role in regulating the body's immune response to infection and disease.
Until very recently, Parkinson’s had been thought a disease that starts in the brain, destroying motion centers and resulting in tremors and loss of movement. New research published this week, shows the most common Parkinson’s gene mutation may change how immune cells react to generic infections like colds, which in turn trigger the inflammatory reaction in the brain that causes…
While gastritis and gastric ulcer disease used to be put down to stress and dietary factors, it was discovered in the 1980s that the actual culprit is infection with a bacterium, H. pylori. This pathogen is now classed as a type I carcinogen by the WHO, as it is the major risk factor for development of gastric carcinoma. Attempts to develop a vaccine against H. pylori have been unsuccessful and…
The immune system is a complex and precisely regulated system. Various activating and inhibiting signals ensure that the immune cells combat pathogenic agents without eliciting a potentially harmful response to its own structures and cells. However, if those two forces are imbalanced, the immune cells may attack and damage cells and tissue of the body itself, which will result in the development…
Loyola University Medical Center is the only Chicago center that participated in the pivotal clinical trial of a groundbreaking cancer treatment that genetically engineers a patient's immune system to attack cancer cells. Patrick Stiff, MD, director of Loyola's Cardinal Bernardin Cancer Center, is a co-author of the study, published in the New England Journal of Medicine. The treatment used in…
Cancer therapies including radiation and chemotherapy seek to treat the disease by killing tumor cells. Now a team including researchers at Beth Israel Deaconess Medical Center (BIDMC) have shown that the dead and dying cancer cells generated by chemotherapy and targeted cancer therapy paradoxically trigger inflammation that promotes aggressive tumor growth. In a study published today in the…
