ELISPOT is one of the most common techniques to identify CD8+ Tcell responses to a given antigen.96,97 Quantitative ELISPOT output is correlated with the strength of the antigen-specific Tcell response, although it cannot be used to determine the absolute number of antigen-specific Tcells. Galon J., Bruni D. Approaches to treat immune hot, altered and cold tumours with combination immunotherapies. Adapted with permission from presentation by Chen and Mellman14 and Song etal.16, To strengthen anti-tumor immunity, TCVs must activate tumor-associated antigen-specific CTLs, and thus targeting neoantigens expressed on a tumor cell surface via the use of a personalized TCV may be an effective strategy. Patients harbor extensive variability in tumor neoantigen expression and clonality that gives rise to evasion of immune effectors and formation of resistance mechanisms, which are key challenges to reducing variability and increasing efficacy for immunotherapies such as TCVs.37,38 Tumors with high neoantigen intratumoral heterogeneity have a higher degree of branched mutations that give rise to an increased amount of subclones expressed with specific neoantigens, resulting in weaker neoantigen-specific Tcell responses.39 Provided that Tcell infiltration and anti-tumor effect are related to selected antigens and the percentage of tumor cells expressing selected antigens, high fractions of subclonal neoantigens have had a negative impact on the response to immunotherapy.35 Innovative multi-epitope approaches targeting more neoantigens by multiplexed personalized TCVs in addition to multi-regional tumor sampling that account for temporal changes following longitudinal liquid biopsy at follow-up may be key to combating tumor antigen heterogeneity,39,40 allowing for diverse targeting of both dominant subclones and low-abundance neoantigens to increase Tcell reactivity.
