Immunometabolism involves glycolysis, tricarboxylic acid cycle, and pentose phosphate pathway and amino acid metabolism and other intracellular metabolic pathways, which play a vital role in regulating immune cell responses. In particular, the metabolism of amino acids such as tryptophan (Trp), ... Views: 315
In-progress Drugs
There is an urgent need for broad-spectrum antiviral drugs to treat infections caused by emerging arboviruses. Some experts believe that one medicine for one type of vector insect is not enough to deal with outbreaks like the Zika pandemic. However, dozens of antiviral ... Views: 313
In the human genome, about 8% of the DNA is the remnants of retroviruses that infect humans or human ancestors in ancient times, which have become part of the human genome. Some of these sequences can even be traced back to hundreds of millions of years ago.

ADC targeting Trop-2
Trophoblast cell surface antigen 2 (Trop-2) is a transmembrane glycoprotein encoded by the tumor-associated calcium signal transducer 2 (TACSTD2) gene located in the 1p32 region of chromosome, and is a new target for the treatment of solid tumors. It acts as a calcium ... Views: 308
Phage display technology is a powerful gene expression screening technology, which was first described by SmithMl et al. in Science in 1985. The basic principle is to clone the gene of the foreign protein into the genomic DNA of the phage, thereby expressing the specific foreign protein on the ... Views: 308
Antibody Library
According to the source and use of antibody genes, antibody libraries are divided into immune antibody library (https://www.creative-biolabs.com/immune-antibody-library-services.html) and general antibody library. The antibody genes of the immune antibody library are derived ... Views: 303
With the increasingly fierce competition in the field of oncology drug R&D, the exploration of various drug forms based on established drug targets is a relatively low-risk R&D option. However, the commercialized drug targets that have been successfully operated are already very competitive. ... Views: 301
Alzheimer's disease is a neurodegenerative disease with insidious onset and progressive development, of which the clinical features are mainly cognitive impairment, abnormal mental behavior, and decline in social life function.

There are three key points in RNA drug R&D.
First, the immunogenicity of RNA drugs: Because foreign RNA will be recognized by the immune system as a signal of virus interference, RNA drugs will more or less stimulate the immune system and cause a series of side effects.
Second, the ... Views: 297
In the emergency response to the COVID-19 epidemic, the first vaccines to be released are all based on mRNA technology. Recently, the "double mutation" mutant virus appeared in India, and mRNA vaccine has once again been highlighted due to its short research cycle.
