Understanding the Role of Metabolism in CD8⁺ T Cell Function

Cancer immunotherapies live or die by one often-overlooked factor: cellular metabolism. This is especially true for CD8⁺ T cells - the immune system's frontline warriors. These cells completely reshape their metabolic wiring to:

Fuel rapid proliferation upon activation
Maintain energy-intensive killing functions
Persist in nutrient-starved tumor environments

Our Solution: Creative Biolabs' specialized testing platform pinpoints exactly how metabolic tweaks affect T cell performance. We measure what matters:

Activation markers
Cytotoxic potency
Exhaustion resistance
Memory cell formation

Service Portfolio: Core Assays and Analytical Modules

Cell-Based Model Development Service

A robust in vitro model is the foundation of reliable immunometabolic studies. Our team specializes in the establishment of custom CD8⁺ T cell models, including primary human or mouse CD8⁺ T cells and engineered lines with defined metabolic profiles. These models are optimized for assessing nutrient dependency, metabolic flexibility, and mitochondrial dynamics under various therapeutic conditions.

CD8⁺ T Cell Proliferation Assay Service

Proliferation is a key indicator of CD8⁺ T cell readiness and resilience following stimulation. We offer a variety of proliferation assays—including CFSE dilution, BrdU/EdU incorporation, and real-time impedance-based analysis—designed to quantify how specific metabolic interventions influence clonal expansion. Assays are performed under conditions mimicking tumor microenvironment stressors such as hypoxia or glucose restriction.

CD8⁺ T Cell Differentiation Assay Service

T cell differentiation into effector, central memory, or exhausted phenotypes is closely tied to metabolic reprogramming. Our differentiation assays leverage surface marker profiling (e.g., CD44, CD62L, PD-1, TIM-3) and intracellular staining (e.g., T-bet, Eomes) to evaluate the phenotypic trajectory of CD8⁺ T cells in response to metabolic modulators. These insights are critical for predicting therapeutic persistence and antitumor capacity.

Tumor Cell Cytotoxicity Assay Service

We employ high-throughput co-culture assays using luciferase- or fluorescence-labeled tumor targets to assess the cytotoxic efficiency of metabolically modulated T cells. Additional endpoints such as cytokine secretion (IFN-γ, TNF-α), degranulation (CD107a), and apoptosis induction (Annexin V/PI) are also available.
