Summary
This study proposes mapping the human toxome to identify nontoxic chemical concentrations. This approach utilizes omics technologies and pathways of toxicity (PoT) for 21st-century toxicology.
Area of Science:
- Toxicology
- Computational Biology
- Biotechnology
Background:
- Regulatory toxicology is being reshaped by new strategies focusing on in vitro and in silico methods.
- Current approaches are shifting towards mechanism-based assessments and understanding toxicant modes of action.
Purpose of the Study:
- To propose the concept of mapping the human toxome, encompassing all pathways of toxicity (PoT) in humans.
- To enable conclusive identification of non-toxic substances or concentrations based on triggered PoT.
Main Methods:
- Leveraging omics technologies for large-scale identification of PoT.
- Developing high-throughput test batteries based on known PoT.
- Extending the concept of PoT mapping to the entirety of human toxicology.
Main Results:
- A framework for mapping the human toxome is proposed.
- The potential to definitively identify non-toxic substances and concentrations is outlined.
- The concept supports the development of advanced toxicology testing strategies.
Conclusions:
- Mapping the human toxome is a crucial step for implementing 21st-century toxicology.
- This initiative could form the core of a Human Toxicology Project.
- The approach promises more accurate and efficient chemical safety assessments.

01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
01:29Sources of Food Contamination
Contamination of food by microbial agents and natural toxins poses significant risks to public health. These hazards can be introduced at various points across the food supply chain, ranging from environmental sources to processing and storage stages. Understanding these contamination pathways is critical for developing strategies to ensure food safety.Seafood is particularly vulnerable to contamination through both environmental exposure and microbial colonization. Toxins from harmful algal...
01:12Bacterial Toxins
Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...
01:21Toxicokinetics: Overview
Studies that assess how a drug is absorbed, distributed, metabolized, and excreted (ADME) at toxic doses are termed toxicokinetics. Understanding toxicokinetics helps predict adverse drug reactions (ADRs) and manage toxicity in humans.Toxicokinetics differs from pharmacokinetics mainly in the dose levels studied, with toxicokinetics focusing on higher toxic doses. The kinetics at these levels can be non-linear due to altered physiological processes. Toxicodynamics examines the relationship...
