One of the main obstacles in drug development is how to deliver drugs effectively to target cells. In general, macromolecules such as proteins and mRNA cannot penetrate the cell membrane because the cell membrane has acquired protective mechanisms through evolution. However, viruses can deliver their genetic material into cells. Therefore, viruses and virus-like particles are widely used to ...

Antibodies (Abs) are essential components of the adaptive immune system, which can combat infections and other harmful agents. Produced by B cells, Ab is either secreted or expressed on the plasma membrane at the present of B cell receptors (BCRs). Each Ab comprises two heavy chains (VH) and two light chains (VL). The VL each include a constant region varing only across different classes and ...

In eukaryotic cells, the 3' end of mRNA is often extended with a poly(A) tail, a sequence of purine nucleotides. The poly(A) tail is a long chain of adenosine nucleotides of variable length. This tail is crucial for mRNA stability, transport, and translation. The analysis of mRNA's 3' poly(A) tail is a vital technique in studying the polyadenylation at mRNA molecules' 3’ ends, with significant ...

Drug affinity responsive target stability is a label-free small molecule probe technique under chemical proteomics first proposed by Lomenick et al. in 2009, which makes it possible to track and identify target proteins whose stability changes after binding with small molecules. To date, Drug affinity responsive target stability has been a focus in tracking proteins in animals, fungi, bacteria, ...

Protein-based macromolecular drugs, typically organic compounds with molecular weights exceeding 1000, depend on cellular biosynthesis and are also known as biologics. Compared to traditional small molecule drugs, protein drugs are characterized by their high potency, strong specificity, low toxicity, clear biological function, and conducive to clinical application. Protein drugs are the ...

Receptors are biomolecules that can bind with hormones, neurotransmitters, drugs, or intracellular signaling molecules and are capable of inducing changes in cellular function. Receptors are categorized based on their cellular location into cell surface receptors and intracellular receptors. Each receptor typically has two active sites: one that recognizes and binds to the ligand and another ...

Humans are highly organized systems comprised of approximately 3.72×1013 cells of various types, which maintain proper organ function and normal cellular homeostasis. Despite significant and revolutionary discoveries in the field of cell biology, the heterogeneity of cells still requires further investigation. Single-cell RNA sequencing (scRNA-seq) has become the latest method for revealing the ...

Bioactive peptides are short protein fragments of 2-50 amino acids in length that are linked by covalent bonds (called amide bonds or peptide bonds). Bioactive peptides have the advantages of simple structure, high biological activity, high specificity and low toxicity, and have broad prospects in the design and development of new peptide ...

The inauguration of monoclonal antibodies (mAbs), derived from mice, were immunogenic in humans. These molecules were first synthesized in 1975 by Georges Köhler and César Milstein through the use of hybridoma technology. Later, in 1984, another milestone was achieved with the production of chimeric human antibodies via recombinant DNA technology. Hybridoma technology facilitates the creation of ...

T cells play a vital role in destroying pathogens and monitoring pathological cells. They are able to distinguish between self-antigens and non-self-antigens by surface T cell receptors (TCRs). Most human T cells express the classical TCRs, which consists of TCRα and TCRβ chains co-expressed with CD3 chains (γ, δ, ε, and ζ). The TCRα and TCRβ chains are composed of a variable (V) and a constant ...

Monoclonal antibodies (mAbs) are monovalent proteins expressed by B cells, capable of precisely targeting 3D epitopes, which makes it a compelling therapeutic option. Over 70 monoclonal antibody drugs have received FDA approval. Monoclonal antibody drugs dramatically transform modern medicine by offering targeted treatments for a variety of diseases. These antibodies specifically activate immune ...

mRNA medication is a novel therapeutic method that utilizes messenger RNA (mRNA). mRNA is a sequence of ribotide that encodes for proteins and can express specific proteins through the translation process within cells. The core principle of mRNA medications is to introduce designed mRNA molecules into the patient's body to produce proteins needed for treatment by utilizing the host cell's ...

Antibodies bind to various antigens with high affinity and specificity, playing a crucial role in adaptive immune response to infections and can also mediate autoimmune diseases by targeting self-antigens. Antibodies facilitate immunity by inhibiting critical stages of a pathogen's replication cycle, such as receptor binding and cellular entry, activating the complement system, or initiating ...

Short chain fatty acids (SCFAs) are a subgroup of saturated aliphatic fatty acids containing 2-5 carbon atoms, with acetate (C2), propionate (C3), and butyrate (C4) being the most abundant. They are the final products of dietary fiber fermented by beneficial coliform bacteria. Humans lack enzymes capable of degrading large amounts of dietary fiber, which passes undigested through the upper ...

Proteolysis targeting chimera (PROTAC) drugs offer a novel approach to disease treatment by leveraging the body's innate protein degradation pathways. In contrast to traditional small-molecule inhibitors, PROTAC drugs promote the degradation of specific proteins rather than directly inhibiting their function, thus mitigating or eliminating their role in disease progression. ...
