Scientists combine 3D bioprinting and computer modeling to study cancer metastasis in blood vessels

Lawrence Livermore National Laboratory scientists have paired 3D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis.

Oral sex can trigger bacterial vaginosis

A new study published in the journal PLOS Biology has revealed diverse microbial populations can facilitate vaginal colonization of pathogens, which in turn can prolong the characteristics of bacterial vaginosis, a condition characterized by an imbalance of vaginal microbiome. The study findings also provide evidence linking oral sex with bacterial vaginosis.

Monoclonal antibodies may be a better choice than convalescent plasma for treating COVID-19

A team of researchers from the Netherlands demonstrated that prophylactic treatment with a high dose of human convalescent plasma or by using concentrated monoclonal antibodies could protect against disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in an animal model. However, no protective effect was observed with a ten-fold lower dose of convalescent plasma. The results are currently available on the bioRxiv* preprint server.

Raccoon dogs potential intermediate host for SARS-CoV-2

Researchers at the Friedrich Loeffler Institute in Germany have conducted a study demonstrating that raccoon dogs were a potential intermediate host in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

New bioluminescent reporter developed to track DNA double stranded break repair

A new bioluminescent reporter that tracks DNA double stranded break repair in cells has been developed by researchers from Massachusetts General Hospital and the Academia Sinica in Taiwan.

Macaques show low neutralizing antibody and cellular immune response to SARS-CoV-2

A new study published on the preprint server bioRxiv* in August 2020 presents a cynomolgus macaque model that develops symptomatic SARS-CoV-2 infection in a mild form, with low or no antibody responses, making it suitable to study human responses to vaccines and drugs targeting the virus.

New type of immunotherapy extends survival of mice with triple negative breast tumors

Immunotherapies for cancer - treatments that prime the immune system to attack tumors - are valuable weapons in the anti-cancer arsenal. But some cancers are more difficult to target with this strategy than others.

Potential inhibitors of SARS-CoV-2 identified

Now, a new study published on the preprint server bioRxiv in August 2020 reports the discovery of two inhibitors of the helicase enzyme, which is essential for viral replication and the most highly conserved non-structural coronavirus (CoV) protein.

SARS-CoV-2 spike pocket is a putative target for antiviral design

In a methodologically rigorous study, researchers from the University of Oxford have recently shown how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein harbors a lipid-binding pocket which modulates the stability of the prefusion trimer and provides conformational shielding from antibodies. Their findings are currently freely available on the bioRxiv* preprint server.

Influenza-virus-based vaccine platform another viable option against SARS-CoV-2

In a novel proof of concept study, published on the bioRxiv preprint server, U.S. researchers used attenuated influenza viral particles that express severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain to induce neutralizing antibodies in mice – unveiling another viable vaccine candidate for preventing coronavirus disease (COVID-19).

Natural controllers shed light on immunity mechanisms against hepatitis B

Infections in humans caused by the hepatitis B virus (HBV) represent a major public health problem. Despite the availability of effective protective vaccines, more than 250 million individuals worldwide are chronically infected according to WHO estimates.

SUTD scientists use 3D printing to create heart cells from stem cells

All humans start out from a single cell which then divides to eventually form the embryo. Depending on the signals sent by their adjacent cells, these divided cells are then developed or differentiated into specific tissues or organs.
