New analysis reveals distinct differences between molecular profiles of 3D and 2D cultured cells

Oncotarget published "Comparative microsomal proteomics of a model lung cancer cell line NCI-H23 reveals distinct differences between molecular profiles of 3D and 2D cultured cells" which reported that to ascertain phenotypical differences between these two distinct culture conditions, these authors carried out a comparative proteomic analysis of a membrane fraction obtained from 3D- and 2D-cultured NSCLC model cell line NCI-H23.

Investigational gene therapy can restore immune function in children with inherited immunodeficiency disorder

An investigational gene therapy can safely restore the immune systems of infants and children who have a rare, life-threatening inherited immunodeficiency disorder, according to research supported in part by the National Institutes of Health.

Horizontal transmission route is responsible for HTLV-1 uveitis

Human T-cell lymphotropic virus type-1 (HTLV-1) is a retrovirus similar to human immunodeficiency virus (HIV) and has mostly been thought to be transmitted vertically (mother-to-child), or horizontally (sexually or parenterally (e.g. via blood transfusion)).

Diabetes drug appears to exploit vulnerability of AIDS-causing retrovirus HIV

A team led by scientists at the UNC School of Medicine discovered an important vulnerability of the AIDS-causing retrovirus HIV, and has shown in preclinical experiments that a widely used diabetes drug, metformin, seems able to exploit this vulnerability.

Retroviruses invading the koala germline contribute to high cancer rates

Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss - accelerated by last year’s devastating bush fires – domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer.

SHREK proteins mediate broad spectrum antiviral host immunity, including against SARS-CoV-2

A new preprint posted to the bioRxiv server demonstrates that similar mucins and mucin-like proteins cannot only suppress HIV-1 infectivity via blockage of viral attachment to the host cells but can block infection by multiple enveloped viruses.

Study reveals innovative gene therapy approach to regenerate functional new neurons

Spinal cord injury (SCI) often causes disability and seriously compromises quality of life. While decades of research have made significant progress in axonal regeneration after SCI, most of the interventions have not been translated into clinical therapies.

ACE2 and TMPRSS2 not the only virus-receptors to mediate SARS-CoV-2 entry

However, a recent study published on the preprint server bioRxiv in November 2020 uncovers the major role played by the N-terminal domain of the SARS-CoV-2 virus in host infection. This could be of great use in measuring the usefulness of antibodies used in convalescent plasma therapy for COVID-19.

New lab test for detection of SARS-CoV-2 antibodies gives results more quickly than existing assays

Knowing you have developed antibodies against the SARS-CoV-2 virus after recovering from COVID-19 doesn't tell you everything about your immunity.

Study on domestic cats and dogs in COVID-19+ households

A recent survey conducted by a team of scientists from France reveals that pets living with confirmed coronavirus disease 2019 (COVID-19) patients have a high prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. The study is currently available on the bioRxiv* preprint server.
