Novel nanoparticle technology can decipher protein structures and help access drug targets

Researchers at Karolinska Institutet, Sweden, have developed a nanoparticle technology that can be used to stabilise membrane proteins so that their structure can be studied in a lipid environment. The method, described in Nature Methods, makes it possible to access drug targets that previously could not be investigated and therefore potentially allows for the development of novel drugs, therapeutic antibodies and vaccines.

Scientists track rare potent antibodies in HIV-infected individual

One of the most crucial and elusive goals of an effective HIV vaccine is to stimulate antibodies that can attack the virus even as it relentlessly mutates.

Unlocking H5N1 virus replication: an interview with Martin Blackledge

We were able to show that one small domain of the polymerase, the part that is essential for entry of a piece of the polymerase into the cell nucleus, changes its conformation to allow it to interact with the transporter protein than takes it into the nucleus.

Revealing dynamic protein complexes with NMR: an interview with Elisar Barbar

Most proteins are involved in interactions with one or a few functional ligands, but some proteins, like light chain 8 (LC8), have numerous binding partners. LC8 interacts with more than 100 functionally different proteins, from viral proteins to motor proteins to proteins involved in cell division.

Researchers identify protein structure linked to pain and heat perception

Touch a hot stove, and your fingers will recoil in pain because your skin carries tiny temperature sensors that detect heat and send a message to your brain saying, "Ouch! That's hot! Let go!"

Researchers identify 124 protein targets of artemisinin in most pathogenic malaria parasite

A team of researchers from the National University of Singapore (NUS) has uncovered the mystery behind the potent parasite-killing effect of artemisinin, a drug that is considered to be the last line of defence against malaria. Given the emergence of artemisinin resistance, these findings could potentially lead to the design of new treatments against drug-resistant parasites.

TSRI scientists track how HIV-fighting antibodies develop over time

In a new study, a team led by scientists at The Scripps Research Institute tracked how a family of these HIV-fighting antibodies develops over time. The research shows how a future vaccine might trigger the immune system to produce these antibodies more effectively.

TSRI-led study shows how different drugs regulate protein linked to asthma, obesity and diabetes

A new study, led by scientists at The Scripps Research Institute, shows how different pharmaceutical drugs hit either the "on" or "off" switch of a signaling protein linked to asthma, obesity and type 2 diabetes.

Study points to new avenue for developing potential strategies to thwart HIV virus

Nearly 37 million people worldwide are living with HIV. When the virus destroys so many immune cells that the body can't fight off infection, AIDS will develop. The disease took the lives of more than a million people last year.

First computational method based on evolutionary principles developed to predict protein dynamics

Researchers from the Structural Biology Computational Group of the Spanish National Cancer Research Centre, led by Alfonso Valencia, in collaboration with a group headed by Francesco Gervasio at the University College London (UK), have developed the first computational method based on evolutionary principles to predict protein dynamics, which explains the changes in the shape or dimensional structure that they experience in order to interact with other compounds or speed up chemical reactions.
