Revealing receptor-ligand interactions of atypical antipsychotic drugs and screening anti-schizophrenia ingredients in Magnolia officinalis based on 5-HTR2A-SNAP-Tag/CMC and DRD2-SNAP-Tag/CMC models.

Schizophrenia is a serious mental illness with unknown etiology, and shows increasing incidence and high lifetime prevalence rate. The main receptors related to the disease are DRD2 and 5-HTR2A. Thus, a comprehensive understanding of the interaction mode between antipsychotic drugs with relevant receptors is very important for developing more effective drugs.

Application of SNAP-tag-EGFR cell membrane chromatography model in screening antitumor active components of Silybum marianum (L.) Gaertn.

The SNAP-tag-epidermal growth factor receptor (SNAP-tag-EGFR) cell membrane chromatography (CMC) model is a powerful tool for investigating ligand-receptor interactions and screening active ingredients in traditional Chinese medicine. Most tyrosine kinase inhibitors (TKIs) target epidermal growth factor receptors. However, TKIs associated with significant side effects and drug resistance must be addressed immediately.

A new MAS-related G protein-coupled receptor X2 cell membrane chromatography analysis model based on HALO-tag technology and its applications.

Cell membrane chromatography (CMC) is an effective method for studying receptors with multiple transmembrane structure such as MAS-related G protein-coupled receptor X2 (MrgX2). CMC relies on the maintenance of the complete biological structure of a membrane receptor; however, it needs to be further improved to obtain a more convenient and stable CMC model. In the present study, the haloalkane dehalogenase protein tag (HALO-tag) technology was used to construct a new MrgX2/CMC model.

Establishment of angiotensin-converting enzyme 2 and cluster of differentiation 147 dual target cell membrane chromatography based on SNAP-tag technology for screening anti severe acute respiratory syndrome coronavirus 2 active components.

Patients have different responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and these may be life-threatening for critically ill patients. Screening components that act on host cell receptors, especially multi-receptor components, is challenging. The in-line combination of dual-targeted cell membrane chromatography and a liquid chromatography-mass spectroscopy (LC-MS) system for analyzing angiotensin-converting enzyme 2 (ACE2) and cluster of differentiation 147 (CD147) receptors based on SNAP-tag technology provides a comprehensive solution for screening multiple components in complex samples acting on the two receptors.

Methylparaben as a preservative in the development of a multi-dose HPV-2 vaccine.

The human papillomavirus (HPV) vaccine is the simplest, most economical, convenient, and effective method of preventing cervical cancer. However, the current HPV vaccine is supplied as a single-dose vial with a relatively high cost per dose, which hinders its supply to low- and middle-income countries (LMICs), where the demand for HPV vaccine is highest. Therefore, it is necessary to develop a multi-dose HPV vaccine to promote large-scale affordable vaccination in LMICs.

Development of recombinant COVID-19 vaccine based on CHO-produced, prefusion spike trimer and alum/CpG adjuvants.

COVID-19 pandemic has severely impacted the public health and social economy worldwide. A safe, effective, and affordable vaccine against SARS-CoV-2 infections/diseases is urgently needed. We have been developing a recombinant vaccine based on a prefusion-stabilized spike trimer of SARS-CoV-2 and formulated with aluminium hydroxide and CpG 7909.
