Summary
High-content screening (HCS) advances drug discovery for cryptosporidiosis. A new high-content imaging (HCI) assay in host cells enables efficient compound screening and characterization for this parasitic diarrheal disease.
Area of Science:
- Parasitology
- Drug Discovery
- Cell Biology
Background:
- Cryptosporidiosis is a diarrheal disease caused by Cryptosporidium parasites.
- These parasites are obligate intracellular pathogens, requiring host cells for in vitro culture.
- Drug discovery for cryptosporidiosis is limited by assay development challenges.
Purpose of the Study:
- To establish a high-content imaging (HCI) assay for Cryptosporidium drug discovery.
- To enable phenotypic characterization of compounds targeting Cryptosporidium parasites.
- To facilitate large-scale screening of potential anti-cryptosporidial agents.
Main Methods:
- Development of a 384- or 1536-well format high-content imaging (HCI) assay.
- Utilizing HCT-8 human ileocecal adenocarcinoma cells as a host cell system.
- Employing high-content screening (HCS) for phenotypic analysis of infected cells.
Main Results:
- An established HCI assay for Cryptosporidium-infected cells was described.
- The assay allows for high-throughput screening of numerous compounds.
- The assay is effective for phenotypic characterization of known active compounds.
Conclusions:
- High-content screening (HCS) provides a powerful platform for cryptosporidiosis drug discovery.
- The developed HCI assay is a valuable tool for identifying and characterizing novel anti-parasitic compounds.
- This approach leverages biologically relevant systems for effective therapeutic development.

01:26Drug Discovery: Overview
11.1K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

02:16Stereotype Content Model
15.4K
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...

Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.

02:33Distribution of Cytoplasmic Content
4.6K
Cytokinesis segregates a cell’s chromosomes and organelles into its daughter cells. Organelles divide and grow prior to cell division but cannot be synthesized de novo; therefore, cells must receive at least one copy of each organelle to survive. Currently, many of the details of how the organelles are distributed are not yet fully elucidated.
Distribution of cytoplasmic determinants
The cytoplasm contains various organelles, as well as salts, proteins, and water. The distribution of...

01:10Moisture Content and Bulking of Aggregate
424
The moisture content of aggregates is a crucial factor in construction, particularly in concrete mixing, as it influences the total water required in the mix. Moisture content represents the water coated on the exterior surface of the aggregate existing in a saturated and surface-dry condition. The total water content of a moist aggregate is the sum of its moisture content and water absorption.
When aggregates are exposed to rain or sit in stockpiles, they absorb moisture, which must be...

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
