HKUST's Meta-analysis Shows SARS-CoV-2 Variants Unlikely to Affect T Cell Responses
In a new study, scientists at The Hong Kong University of Science and Technology (HKUST) have revealed that most T cell epitopes known to be targeted upon natural infection are seemingly unaffected by current SARS-CoV-2 variants.
In their latest research, the team compiled and analysed data from 18 immunological studies of T cell responses involving over 850 recovered COVID-19 patients from across four continents who are well-distributed in age, gender, disease severity and blood collection time. They demonstrated that T cells in these patients targeted fragments (epitopes) of almost all of the virus' proteins, including the spike protein that is a main target of many existing vaccines. As an important finding, based on analysis of over 850,000 SARS-CoV-2 genetic sequences from around the world, most of these epitopes appeared to be unaffected by the current variants of concern.

HKUST Researchers Develop a Novel Raman Spectroscopy Platform to Characterize Intrinsically Disordered Proteins in Dilute Solution
It is challenging to analyze proteins at low concentrations, especially for those in a mixture of various conformations such as intrinsically disordered proteins (IDPs). A research team led by Prof. HUANG Jinqing, Assistant Professor of Department of Chemistry at The Hong Kong University of Science and Technology (HKUST), has developed optical tweezers-coupled Raman spectroscopy that can directly probe the structural features of alpha-synuclein, an IDP closely linked to Parkinson’s disease, at the physiological concentration by focusing on individual protein molecules.

HKUST Researchers Unlock the Micro-Molecular Physiochemical Mechanism of Dental Plaque Formation
An inter-disciplinary team of researchers led by Prof. Qian Peiyuan, Chair Professor at the Hong Kong University of Science and Technology (HKUST)’s Department of Ocean Science and Division of Life Science has unraveled how a novel microbial small molecule released by Streptococcus mutans (S. mutans) – a bacterium commonly found in the human oral cavity – is connected to dental caries development using a synthetic biology approach, offering new insights to the health impact of the human oral microbiota and facilitating future research on the prevention of tooth decay. The research findings were recently published in the prestigious scientific journal Nature Chemical Biology and reported by Nature as one of the research highlights.
