DNA methylation levels are age-dependent and can vary over time. When an individual's DNA methylation age is greater than the actual age, this means that the individual is in an age acceleration state, and which may be associated with many aging manifestations, disease development, and even death. DNA Methylation Age AccelerationAge acceleration can be defined as the difference between the DNA methylation age and the actual age, or as the residual resulting from regressing the DNA methylation age on the actual age. In comparison... more
Cancer vaccines represent a promising strategy to induce specific and durable immune responses against tumor antigens (TAs), which are mainly proteins overexpressed in tumor tissue and play a central role in tumor initiation, progression and metastasis. Cancer vaccines have many superior advantages, including minimal non-specific effects, relative non-toxicity, and induction of persistent immunological memory and so on. Compared with standard chemo- and immunotherapies, cancer vaccines have reduced adverse reactions, higher therapeut... more
New research has found that stem cell-derived neurons predict psychosis and cognitive deficits in patients with schizophrenia. In addition, adult neural stem cells play important roles in cognitive functions, including spatiotemporal memory encoding and contextual discrimination, which have been shown to be strongly associated with many psychiatric disorders, such as schizophrenia.Learn more：Neural stem cell characterization
Amino acid composition analysis is the gold standard for accurate quantification of peptides, proteins, antibodies, and other samples. It is often desirable to know the amino acid composition of a sample before finding the sequence information of the sample. A common method for determining amino acid composition is commonly referred to as amino acid analysis, which can be used to determine the amino acid composition, composition, and content of amino acids, peptides, polypeptides, proteins, and antibody samples. Amino acids anal... more
The cell cycle is a complex process that involves the growth and division of a cell. It is divided into four phases: G1, S, G2, and M. During each phase, the cell undergoes a series of events that prepare it for the next phase. Cell cycle checkpoints are control mechanisms that ensure that the cell cycle proceeds in a timely and orderly manner. There are three major cell cycle checkpoints:· G1 checkpoint: This checkpoint occurs at the end of the G1 phase. It ensures that the cell has grown to a sufficient size and that... more
Gene
editing is one of the latest breakthroughs in biology. The well-known
CRISPR-Cas gene editing system confers immunity against foreign DNA to
prokaryotes (organisms lacking a cell nucleus). Since the discovery of CRISPR
gene editing technology, scientists have revealed how CRISPR-cas proteins
evolved from their precursors. This knowledge will help them develop other
small new genome editing tools for gene therapy.
At
the University of Tokyo, Professor Osamu Nureki's team worked to identify the

Microplastics, a "stealth killer" that threatens the Earth's environment and human health, are now ubiquitous. In previous studies, scientists have found traces of microplastics in environments such as the deep sea, Everest roof, seafood, human placenta, and baby feces. Once such non-degradable particles with a particle size of less than 5 mm enter the human body, it may interfere with the human endocrine system and cause long-term effects on human health. Furthermore, in addition to causing direct harm to the human body, m... more
Alzheimer's disease (AD) presently occupies the topmost position among the most diagnosed neurodegenerative diseases worldwide, with the number of affected people forecasted to reach 100 million by 2050. According to the latest statistics, nearly 44 million people in the world suffer from AD or related dementia, with only one in four being diagnosed with the disease. Currently, the disease has no cure available for its treatment, except for some relief from some of the symptoms. Besides its multifactorial and heterogeneous nature, AD... more
Background of Tau Uptake and SeedingTau proteins are a group of microtubules associated proteins that are mainly located in the central nervous system astrocytes. Tau proteins participate in several biological activities, including regulation of microtubule stabilization and assembly, maintenance of neuronal cytoskeleton, iron export, and axonal transportation. However, tau proteins turn into hyperphosphorylated insoluble aggregates could lead to neurodegenerative tauopathies, such as Alzheimer's disease (AD). The aggregation of tau ... more

Plant
growth is driven by light and is powered by photosynthesis of green leaves. The
same is true for roots that grow in the dark—they receive the products of
photosynthesis, specifically sucrose, or sugar, through a central transport
pathway in the phloem. Dr. Stefan Kircher and Prof. Peter Schopfer from the
Faculty of Biology at the University of Freiburg have shown in experiments
using the model plant Arabidopsis thaliana that sucrose not only ensures the
supply of carbohydrates to the roots, but also acts as a signal tran... more
Exosome in AD: Exosomes have been reported to serve as a role in the treatment of many diseases including central nervous system (CNS) disorders. Due to their small size, exosomes are used as effective carriers that deliver therapeutic drugs to target cells or tissues. Besides, mesenchymal stem cells (MSCs)-derived exosomes also play an essential role in CNS diseases therapies.
exosome lyophilization: Lyophilization is a useful technique that can be used for long-term stable preservation of exosomes. Lyophilized exosome standard is easy to transport and storage, and is stable for over 36 months at 4°C. Besides, lyophilized exosome can be used as control standards for FACS, WB, ELISA and other applications, as well as quantitative calibration standards for foreign and domestic exosomes in biological samples.
exosomal rna isolation kits: Exosomes play a critical role in cell-cell communication by shuttling functional protein or nucleic acid molecules in the target cell. They are involved in a variety of pathological processes such as cancer, infectious and neurodegenerative diseases.

genetically modified T cell: The concept of transferring T cells to patients (adoptive T cell transfers) to treat diseases has been established over the years through ex vivo manipulation, expansion, and reinfusion of T cells targeting specific viruses, for example for the treatment of viral infections, such as cytomegalovirus or Epstein Barr virus infection after hematopoietic stem cell transplantation.
Adnectin-based CAR-T cell:Adnectin can be used as the antigen recognition domain in CAR constructs instead of scFv. We have designed multiple antigen-specific adnectin-CARs. Firstly, mRNA display is used to generate different adnectin clones, which target the target extracellular domain with different affinities. Then, different clones of target-specific adnectins were cloned upstream of the hinge domain to replace the scFv sequence. The adnectin-based extracellular domain is connected by the CD8α hinge and transmembrane domain, CD28... more
