Human Organotypic Models for Anti-infective Research

Area of Science:

• Biomedical Research
• Infectious Disease Research
• Toxicology

Background:

• Human organotypic models are increasingly used in research due to their biological relevance and cost-effectiveness.
• There is a growing need to reduce animal model use in anti-infective research due to data unreliability and ethical concerns.
• Three-dimensional (3-D) human models can enhance the translational value of preclinical data by complementing or replacing in vivo studies.

Purpose of the Study:

• To provide an overview of recent studies using human organotypic models in anti-infective research.
• To highlight the application of these models in various human tissues, including cervix, intestine, lungs, brain, and skin.
• To focus on future applications and methodological protocols for human skin models.

Main Methods:

• Literature review of recent studies utilizing human organotypic models for anti-infective research.
• Focus on models mimicking human cervix, intestine, lungs, brain, and skin.
• Detailed examination of protocols for culturing human skin equivalents and explants.

Main Results:

• Human organotypic models are effectively used across multiple tissue types for anti-infective research.
• These models show promise in reducing and replacing animal studies.
• Specific protocols for human skin models are presented for future applications.

Conclusions:

• Human organotypic models represent a significant advancement in anti-infective research, offering biological relevance and ethical advantages.
• The development and application of these 3-D models are crucial for improving the translational value of preclinical anti-infective studies.
• Future research should leverage these models, particularly human skin equivalents and explants, for novel therapeutic and vaccine development.
