Study demonstrates dynamic and broad-scale immune alterations in COVID-19 patient

A new case report released on the preprint server medRxiv* provides a detailed longitudinal analysis of the immune response associated with a fatal case of coronavirus disease (COVID-19). It highlights the need for addressing the source of hyper inflammation in the treatment approach.

Low CD8 and NK cell counts in the lung linked to high SARS-CoV-2 ACE2 receptor levels

A new study published on the preprint server bioRxiv in April 2020 reports that low levels of specific immune cells, namely, CD8 T cells and NK cells, are linked to higher expression of the ACE2 molecule, which acts as a receptor for the CoV.

Hydroxychloroquine shown to slow recovery for COVID-19 patients

As researchers try to piece together a therapeutic strategy against the ongoing COVID-19 pandemic, a recent retrospective study from Cleveland Clinic Abu Dhabi, assessed the Hydroxychloroquine's efficacy in increasing SARS-CoV-2 viral clearance, finding that it appeared to significantly slow viral clearance in mild to moderately ill COVID-19 patients.

Immunity to coronavirus infection may help stem the pandemic

The raging coronavirus pandemic is causing immense fear and uncertainty across the world. One of the most distressing aspects of COVID-19 disease is the seemingly large number of unknowns. These include the burning question of immunity. Does a person who was sick with the COVID-19 and then recovered or was infected without symptoms, have immunity against re-infection?

Gimsilumab trial starts in first US patient with ARDS and COVID-19

The first American patient with COVID-19 and acute respiratory distress syndrome (ARDS) has been put on the drug gimsilumab at Temple University Hospital, as part of the BREATHE clinical trial. The trial, sponsored by Roivant Sciences, will evaluate the effectiveness of intravenous gimsilumab in preventing death in patients with COVID-19 and ARDS.

'Chaperone protein' protects against autoimmune diseases, mice study shows

Like a parent of teenagers at a party, Mother Nature depends on chaperones to keep one of her charges, the immune system, in line so that it doesn't mistakenly attack normal cells, tissues and organs in our bodies.

Depressive disorders in patients with HIV/AIDS often go unrecognized or untreated

People living with HIV/AIDS are at increased risk of depressive disorders. But all too often, these conditions go unrecognized or untreated, suggests a literature review in the May/June issue of Harvard Review of Psychiatry.

Using 'organs-on-a-chip' to study chronic inflammatory diseases

MIT biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system, on a specialized microfluidic platform seeded with human cells.

Immunotherapy combination can shrink viral reservoir in HIV model

Stimulating immune cells with two cancer immunotherapies together can shrink the size of the viral "reservoir" in SIV-infected non-human primates treated with antiviral drugs, researchers have concluded.

Exploring the biological link between reactivated HSV and neurological disease

Without even knowing it, most of us carry around latent Herpes Simplex Virus in our nervous system- a simple result of being born and living together with others carrying the virus.

Study reports second ever case of a patient to be cured of HIV

A study of the second HIV patient to undergo successful stem cell transplantation from donors with a HIV-resistant gene, finds that there was no active viral infection in the patient's blood 30 months after they stopped anti-retroviral therapy, according to a case report published in The Lancet HIV journal and presented at CROI.

Immune systems of preemies can catch up

According to a new study published in March 2020 in the journal Nature Communications, babies born prematurely up to 32 weeks of pregnancy can quickly catch up on their immune system function after birth, bringing them to a state comparable to term infants.

Cellular metabolism plays key role in dictating the fate decision between pathogenic and regulatory T cells

Patients with autoimmune diseases like multiple sclerosis, inflammatory bowel disease and rheumatoid arthritis have an imbalance between two types of immune system T cells.

New study uncovers human genes controlling HIV infection

Viruses are parasites. The only way they can grow is by hijacking their hosts. When they infect a human host, viruses use human proteins to multiply and modify the human cells to sustain the infection. At the same time, the human host activates defense mechanisms to fight the infection.
