Immunodeficiency News and Research

RSS

Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease is compromised or entirely absent.

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

Humans promote diseases from the animal kingdom

The coronavirus pandemic, which has now infected nearly 19 million and killed more than 712,000 people, most likely originated from bats. Just like other coronavirus outbreaks in the past, a spill-over event or zoonosis caused the viruses to jump from animals to humans.

UCI researchers develop novel molecule for COVID-19 treatment

When the coronavirus pandemic hit, almost everyone at the University of California, Irvine – and colleges across the nation – had to abandon campus.

Penis microbiome is reservoir for bacterial vaginosis-associated bacteria

Previous studies have pointed out that the reproductive microbiomes of partners might be exchanged in bacterial vaginosis (BV). Now, a team of researchers at the University of Illinois in Chicago compared the microbiota of couples before and after the development of BV.

Study shows high SARS-CoV-2 seroprevalence, but low death rate in Malawi's health care workers

A study by researchers from Malawi and United Kingdom reveals a significant discrepancy between predicted coronavirus disease (COVID-19) mortality in the observed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence rates in health care workers and reported deaths in urban Malawi in southeastern Africa, indicating early exposure, but a slow progression of the outbreak. Their findings are currently available on the medRxiv preprint server.

Stabilized prefusion spike vaccine candidate induces powerful immune response

A new research paper by scientists at Janssen Vaccines & Prevention BV, in the Netherlands and published on the preprint server bioRxiv* is based on the assumption that an effective vaccine against these infections will induce neutralizing antibodies and an immune response favoring Th1 immunity.

Researchers identify TLR7 gene that predisposes elderly patients to severe COVID-19

Current observations suggest that the coronavirus SARS-CoV-2 causes severe symptoms mainly in elderly patients with chronic disease.

Spinal cord injuries in mice cause acquired bone marrow failure syndrome

Research conducted at The Ohio State University Wexner Medical Center and The Ohio State University College of Medicine found that spinal cord injuries in mice cause an acquired bone marrow failure syndrome that may contribute to chronic immune dysfunction.

Novel research determines the prevalence of chronic kidney disease

A new study looking at nearly three decades of data from some 54,000 people has determined that the overall prevalence of chronic kidney disease (CKD) for several racial/ethnic and socioeconomic groups in the United States has stabilized in recent years, except Mexican Americans.

Researchers identify specific target sites for DNA methylases

DNA methylation performs an essential function in mammalian ontogeny. It is also known that abnormalities in this process cause the development of cancers such as leukemia.

22 Jul 2020

New tools developed to test the ability of anti-coronavirus antibodies

Researchers at The Rockefeller University in New York have developed new tools to rapidly test the ability of antibodies to neutralize SARS-CoV-2, the novel coronavirus responsible for the COVID-19 pandemic.

How immune cells switch to attack mode

Unraveling a key motif: The T lymphocytes of the immune system work to destroy infected cells or cancer cells. To do so, they have to identify the threat: Molecules perceived as foreign - so-called antigens - bind to the T-cell receptor on the T cell surface.

Pioneering method reveals the dynamics of HIV Gag lattice structure

Viruses are scary. They invade our cells like invisible armies, and each type brings its own strategy of attack. While viruses devastate communities of humans and animals, scientists scramble to fight back.

Likelihood of SARS-CoV-2 transmission may depend on blood type of spreader and recipient

A modeling study by Dr. Peter Ellis from the University of Kent indicates that ABO incompatibility between infected patients and susceptible individuals may actually decrease the transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by 60% or more. His detailed investigation of such "ABO-interference" can be found on the medRxiv preprint server.

New study identifies challenges and opportunities to promote nurse- and midwife-led HIV services

"Nurse-initiated and managed antiretroviral therapy" (NIMART) is an innovative approach to making effective medications more accessible to people living with HIV (PLWH) in low-resource countries.

Study shows how the brain's auditory system is affected by HIV

Even with effective antiretroviral therapy, patients infected with the Human Immunodeficiency Virus (HIV) sustain central nervous system damage.

Whole genome sequencing can improve diagnosis and treatment of patients with rare diseases

A research programme pioneering the use of whole genome sequencing in the NHS has diagnosed hundreds of patients and discovered new genetic causes of disease.

A highly sensitive and specific antibody test for COVID-19

A new proof-of-concept study by UK researchers, currently available on the medRxiv* preprint server, describes the development of an enzyme-linked immunosorbent assay that can be used when lower levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific-antibodies are present in serum and saliva samples.

New test will help better manage patients with severe combined immunodeficiency

A new test developed at CHU Sainte-Justine in Montreal will enable better management of patients with severe combined immunodeficiency.

Research team generates comprehensive developmental map of human T-cells

Chintan Parekh, MD, of The Saban Research Institute of Children's Hospital Los Angeles, has led a team of investigators that generated a comprehensive roadmap for how T-cells develop in the human thymus.
