Abstract

Histopathological analysis of tissues infected with Chikungunya virus (CHIKV), including biopsy and autopsy specimens, can provide valuable insights into the pathogenesis of atypical and fatal cases. By examining tissue architecture and cellular alterations under the microscope, it is possible to identify patterns of injury, inflammation, and cellular degeneration. These morphological findings provide evidence of how the pathogen interacts with host cells and tissues. Moreover, immunohistochemistry may be performed in tissue sections for the detection of viral antigens. Importantly, this technique allows the characterization of diverse biologically relevant targets in tissue samples, such as distinct immune cell subsets, cytokines, and additional molecular markers. This is accomplished by the use of antibodies selected for their specificity toward the antigen of interest. In this chapter, we present a concise overview of how histological analysis and immunohistochemical approaches can enhance the understanding of CHIKV-associated pathological mechanisms.
