Immunology

Overview

Decoding Immune Mechanisms Through Cellular Analysis

Immunology explores how cellular systems recognize specific target molecules, initiate defensive signaling pathways, and maintain biological equilibrium. It serves as an essential foundation for modern biotechnology, biomanufacturing, protein engineering, and advanced cellular diagnostics.

In this program, students isolate immune cell subsets, perform multi-color flow cytometry for immunophenotyping, and measure cell-mediated immune responses in controlled laboratory settings. By mastering quantitative functional assays, participants gain essential skills in experimental design, single-cell analysis, and bio-engineering applications across the broader life science industry.

Selected Topics

Immune Cell Isolation and Subtype Characterization

Students isolate mononuclear cells using density gradient centrifugation and immunomagnetic bead selection to evaluate cellular purity, yield, and viability.

Flow Cytometry and Immunophenotyping Assays

Utilizes multi-color fluorophore-conjugated antibodies to profile cell surface biomarkers and quantify specific lymphocyte populations via flow cytometric gating.

Cell-Mediated Immune Function and Cytotoxicity Assays

Evaluates effector cell cytolytic capacity and target cell clearance through co-culture models, fluorescent viability dye staining, and release quantification.

Cytokine Profiling and ELISA Assays

Measures secreted signaling proteins such as interleukins and interferons during immune activation using sandwich ELISA and microplate quantification.

Phagocytosis and Innate Immune Mechanisms

Investigates macrophage and granulocyte particle engulfment using fluorescent microparticles and live-cell imaging to analyze innate recognition pathways.

Antibody Engineering and Binding Affinity Assays

Explores immunoglobulin domain structures, recombinant antibody preparation, and receptor-antigen binding specificity across target concentrations.

Sample Project Design

In Vitro Generation and Functional Validation of CAR-T Cells

In this guided project, students model the process of engineering T lymphocytes with synthetic chimeric antigen receptors (CARs) and evaluate their antigen-specific activation and targeted effector function in vitro.

Research Question

How does chimeric receptor expression influence antigen-specific cell activation, cytokine release, and target clearance in vitro?

Laboratory Activities

Students execute hands-on experimental protocols, including:

✓ Isolating and culturing primary T lymphocytes using cell separation kits and growth media.
✓ Performing gene delivery or plasmid transfection to express engineered receptor constructs.
✓ Measuring chimeric receptor surface expression using fluorescent antibody staining and flow cytometry.
✓ Co-culturing engineered T cells with antigen-expressing target cells across varied Effector-to-Target (E:T) ratios.
✓ Quantifying target-cell cytotoxicity using viability- or LDH-based assays and measuring cytokine release using ELISA.
✓ Comparing CAR-T cells with non-engineered T-cell controls against antigen-positive and antigen-negative target cells to evaluate antigen-specific activation and cytotoxicity.

Data Analysis & Evaluation

Transforming raw data into meaningful scientific conclusions:

Visual Presentation Students generate multi-parameter flow cytometry dot plots, E:T ratio-dependent target-cell clearance curves, and gating strategies.

Hypothesis Testing Under mentor guidance, participants evaluate whether experimental groups show statistically significant target clearance versus controls.

Next-Step Planning Students critically evaluate construct architecture parameters and design follow-up assays to optimize cellular persistence.
