Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

The Bohr Model

The Bohr Model

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

The Fluid Mosaic Model

The Fluid Mosaic Model

The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Compartment Models: Two-Compartment Model

Compartment Models: Two-Compartment Model

The two-compartment model divides the body into central and peripheral compartments to account for varying blood perfusion rates among organs and tissues, affecting drug distribution. The central compartment includes blood and highly perfused tissues with rapid drug distribution, while the peripheral compartment contains tissues with slower drug distribution. After a single IV bolus dose, the drug concentration is high in plasma and low in tissues. The drug distribution between compartments...

Background:

Translational research requires small molecules with low mammalian cell cytotoxicity.
Vero cell cytotoxicity (CC50) assays are crucial for initial screening.
Identifying non-cytotoxic compounds is essential for therapeutic development.

Purpose of the Study:

Develop naïve Bayesian models to predict and enhance the identification of non-cytotoxic compounds.
Improve the probability of selecting compounds with low Vero cell cytotoxicity.

Main Methods:

Curated 8741 unique small molecules from PubChem Vero cell cytotoxicity assays for training.
Developed Bayesian classifiers using ECFP_6 descriptors and FCFP_6 fingerprints.
Assessed models via internal cross-validation, external tests (193 compounds), and independent validation (1609 compounds).

Main Results:

Bayesian models using ECFP_6 descriptors showed higher accuracy than those using FCFP_6 fingerprints.
The best cytotoxicity Bayesian model demonstrated significant predictive power in external evaluations.
Performance was validated using conventional, chance-corrected statistics, and enrichment factors.

Conclusions:

The novel cytotoxicity Bayesian model possesses sufficient predictive power to guide translational research.
The curated training set is publicly available to aid the chemical tool and drug discovery communities.
This model serves as a valuable tool for selecting small molecules with low Vero cell cytotoxicity.
