There are several challenges faced by researchers in this field:
Complexity of the Immune System: The immune system is highly complex, involving numerous cell types and signaling pathways, making it difficult to predict the effects of various agents accurately. Variability Among Individuals: Genetic and environmental factors can cause significant variability in how individuals respond to immunotoxicants. Lack of Standardized Testing: There is a need for standardized protocols and assays in immunotoxicology to ensure consistent and reliable results.
