Flow Cytometry News and Research

RSS

Flow cytometry is a technique for counting and examining microscopic particles suspended in a stream of fluid. It allows simultaneous multiparametric analysis of the physical and/or chemical characteristics of single cells flowing through an optical and/or electronic detection apparatus.

Hypoxia signaling pathway could lead to COVID-19 treatments

Researchers in Spain have demonstrated that studying the hypoxia signaling pathway could provide opportunities for treating coronavirus disease 2019 (COVID-19).

Discovery of SARS-CoV-2 neutralizing antibodies from a naïve human Ab library

Now, a new preprint research paper published on the bioRxiv server shows how closely the antibodies formed in exposed humans resemble the germline antibody molecules. This could lead to the development of novel therapeutics to counter the pandemic.

ACE2 receptor is responsible for the wide host range of SARS-CoV-2

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is thought to have a zoonotic origin, perhaps originating in a bat coronavirus with an unknown intermediate host. It is not only very infectious but has been found to infect a wide range of mammals, including dogs, cats, ferrets, hamsters, and minks, besides non-human primates. This range may be still higher, claims a recent preprint that appeared in January 2021 on the bioRxiv server.

Traditional herbal medicine Respiratory Detox Shot (RDS) inhibits SARS-CoV, SARS-CoV-2 and Influenza A infection in vitro

As researchers continue to search for antivirals to counter COVID-19, a study presents the potential utility of a decoction called Respiratory Detox Shot (RDS).

Recovered COVID-19 patients exhibit persistent cellular immunity

Researchers at The Rockefeller University in New York have conducted a study showing that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – triggers persistent T cell responses that last for at least six months.

Study highlights previously unknown mechanisms involved in myeloma resistance

A group of researchers led by Maximillian Merz, MD, Assistant Professor of Oncology with the Myeloma team at Roswell Park Comprehensive Cancer Center, conducted the first prospective clinical trial investigating spatial heterogeneity in patients with either relapsed/refractory or newly diagnosed multiple myeloma.

Study evaluates the use of flow cytometry in diagnosing male urethritis

According to the World Health Organization, the global prevalence estimates of sexually transmitted infections for men in 2016 were 2.7% for chlamydia, 0.7% for gonorrhea and 0.6% for trichomoniasis. In men, these and other sexually transmitted infections may lead to urethritis, inflammation of the urethra.

A new potential COVID-19 vaccine candidate: YF-S0

A recent study published in the journal Nature describes the safety and efficacy of a live-attenuated yellow fever 17D (YF17D) vector-based vaccine candidate expressing a non-cleavable form of the spike protein of severe acute respiratory coronavirus 2 (SARS-CoV2).

Good cholesterol helps SARS-CoV-2 enter cells

The researchers explained that the SARS-CoV-2 can infect human host cells after its viral spike protein (SARS-2-S) binds to a cellular surface receptor called the angiotensin-converting enzyme 2 (ACE2).

Study identifies new factor that offers potential strategy for treating obesity

Obesity is a serious global health problem and a risk factor for diseases such as type II diabetes, heart disease and fatty liver disease.

Asymptomatic individuals mount polyfunctional antibody response to SARS-CoV-2

Researchers in France have conducted a study showing that people who are asymptomatic following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – elicit a polyfunctional antibody response to the virus.

Study sheds new light on the immune system response to COVID-19

A team of immunology experts from research organizations in Belgium and the UK has come together to apply their pioneering research methods to put individuals' COVID-19 responses under the microscope.

SARS-CoV-2 immunity may last over six months through antibody evolution and B cell memory

With the coronavirus disease 2019 (COVID-19) pandemic infecting over 52.7 million people around the world, and killing over 1.2 million, a large amount of research has tried to better understand immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes COVID-19.

Immunotherapy drugs trigger inflammatory arthritis in subset of cancer patients

Since doctors began treating cancer patients with immunotherapy drugs called checkpoint inhibitors nearly a decade ago, they have observed that a subset of these patients experience a side effect that clinically looks like inflammatory arthritis.

Pre-existing anti-IFN autoantibodies may worsen COVID-19 in lupus patients

“Our observations suggest that the presence of these autoantibodies may predispose SLE patients to infection with SARS-CoV-2 with a more severe presentation and represent an additional risk factor in this patient population,” write Sarthak Gupta and colleagues from the National Institute of Arthritis and Musculoskeletal and Skin Diseases in Bethesda, Maryland.

5 Nov 2020

Most SARS-CoV-2-infected individuals develop durable B cell-mediated immunity

Researchers from the Johns Hopkins University and The Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, USA, investigated the durability of B cell immunity following SARS-CoV-2 infection and recovery in their recent work published on the preprint server medRxiv.
