ICS and ELISpot for The Study of Cell Response: Choosing the Optimal Method in Immuno-Oncology or COVID-19 Vaccination Trials, Upcoming Webinar Hosted by Xtalks

Share Article

In this free webinar, the featured speaker will discuss the advantages and limitations of ICS and ELISpot for clinical trials and how to design ICS and ELISpot assays for maximal data gathering. Attendees will learn about critical development and validation approaches to consider with ICS and ELISpot assays to fulfill regulatory requirements.

Performing both ELISpot and ICS assays requires a lot of starting material (PBMC isolated from whole blood), which might not be accessible. The question then arises: which method to use? ELISpot or ICS?

Efficacy in a vaccine trial is assessed through the production of protective antibodies against the infectious agent. Measurement of the neutralizing effect of these antibodies is performed through cell-based assays. Over the past years, additional assays have been introduced in vaccine trials in order to get a better understanding of the vaccine’s mode of action on the immune system. These assays allow for the monitoring of T-cell responses in subjects upon vaccination, including the humoral response (supported by CD4 helper T cells) and the elimination of infected cells by CD8 cytotoxic T cells (cellular response).

Flow cytometry and multimer detection can be used to follow an antigen specific T-cell response and reveal a specific TCR. However, this method allows one to follow only one antigen and the functional state (effector/anergic) of the cells remains unknown. Given these limitations, most trials now employ ELISpot and ICS to reveal both the antigen-specificity and the functionality of the immune response induced by the treatment.

Performing both ELISpot and ICS assays requires a lot of starting material (PBMC isolated from whole blood), which might not be accessible. The question then arises: which method to use? ELISpot or ICS? On one hand, the ELISpot is commonly considered more sensitive than the ICS assay while requiring less amount of PBMC. On the other hand, the ICS allows for the measurement of cytokines as well as surface and intracellular markers to generate a more complete cellular profile but consumes more of the precious PBMC material.
