• Cancer is a chronic disease, similar to some viral infections
during which T cells are stimulated chronically
• The immune system plays an important role in the regulation
and outcome of cancer
• The relationship between cancer and the immune system is
highly complex and can take different paths
There are three main theories that shape our understanding of
the immune system in cancer
◦ Human protective cancer immunity by Paul Ehrlich
◦ Cancer immunosurveillance by Burnet and Thomas
◦ Cancer “immunoediting” – The three “E”s
− Elimination
− Equilibrium
− Escape

The immune system’s response to cancer: immunoediting
Strausberg, R.L. (2005) Tumor microenvironments, the immune system and cancer survival. Genome Biology, 6, 211
1. Recognition, infiltrating,
recruiting to induce tumor
death
2. Elimination
3. Promote more tumor death
4. Destroy tumor cells
Tumor cells that
survive the
elimination phase
enter the equilibrium
phase
Tumor cells that have
acquired resistance to
equilibriumenter the
escape phase
Immunoediting – The three “E”s
• Elimination: The immune system has the ability to eliminate tumor cells
• Equilibrium: Poorly immunogenic and immunoevasive transformed cells enter a steady-state phase
• Escape: Edited tumor cells that survive the equilibriumphase enter the escape phase
Two mechanisms of
escape:
• Exhaustion of
immune system
• Acquisition of
mutations

Sample to Insight
Cancer stem cell theory: how do tumors escape the immune system?
Cancer stem cells (CSCs) have immune privileges:
• Serve as the backbone of tumorigenesis, which links the three “E”s of cancer immunoediting
• Are not only long-lived, but also express membrane-bound and soluble factors that enable them to
efficiently modulate immune responses and protect themselves from immune-mediated destruction
• Acquire metastatic potential by undergoing EMT

understanding tumorigenesis and tumor immune escape. Frontiers in Immunology, 5(360),1

Sample to Insight
Tumor escape mechanisms: immunosuppression
Tumors can be classified into two groups:
• Immunologically-ignorant tumors (non-inflamed tumors)
◦ Absence of immune cell infiltration
◦ May be caused by
− Low mutation loads
− Immune tolerance against self-antigens
− Lack of essential chemokines and other molecules necessary for T cell
homing to tumor sites
• Immunologically-responsivetumors (T cell-inflamed tumors)
◦ Presence of immune cell infiltration
◦ May be caused by
− Intrinsic T cell immune-inhibition
− Extrinsic tumor-related T cell immunosuppression
9

Sample to Insight
Tumor escape mechanisms: immunosuppression
Extrinsic tumor-related T cell immunosuppression:
• Involves extrinsic inhibitory molecules, such as TGF-β,
IL-10 and indoleamine 2,3-dioxyenase (IDO)
• Negatively impacts T cell function in the TME and the
recruitment of anti-inflammatory cells, including
◦ Tolerogenic antigen presentingcells (APCs)
◦ Regulatory T cells (Tregs)
◦ Myeloid derived suppressor cells (MDSCs)
Intrinsic T cell immunosuppression:
• T cell “exhaustion” with cancer endogenous immune
checkpoint molecules, such as
◦ Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4)
◦ Programmed cell death 1 (PD-1)
◦ T cell immunoglobulin mucin-3 (Tim-3)
◦ Lymphocyte-activation gene 3 (LAG-3)
• Serves as immunotherapy candidate to increase
endogenous anti-tumor immunity
• An important feature is the loss of secretion of important
molecules, such as IL-2, IFN-γ and TNF-α

Sample to Insight
Regulatory T cells (Tregs) and human cancer
Are Tregs regulating for or against tumor progression?
• Inducible Tregs (iTregs) play a key but dual role in cancer, and their plasticity is
controlled and driven by the microenvironment:
◦ iTregs expand and accumulate in tissues and the peripheral blood of cancer patients
◦ They may suppress anti-tumor immune responses and be responsible for tumor escape
◦ On the other hand, they may down-regulateexcessive inflammation and protect the
patient from tumor development
Regulatory T cells serve as potential
biomarkers
• Monitoring for the frequency and
functions of iTregs (FOXP3) is important
in cancer
• Are post-therapy iTregs beneficial or
harmful for patients undergoing
potentially curative cancer therapies?

for or against tumor progression? Cancer Immunol Immunother, 63(1), 67–72

Title, Location,Date 12
Immune-targeted therapy focused on T cells
Cancer immunotherapy relied on two principal mechanisms of action:
• ‘‘Passive’’ immunotherapy:
◦ Anti-tumor antibodies, e.g. Trastuzumab (aHER2 mAB) or Rituximab (aCD20 mAB)
◦ Adoptive transfer of cytotoxic T and NK cells
• ‘‘Active’’ immunotherapy (mobilize the patient’s immune cells):
◦ Immune checkpoint blockade, eliminating negative signals that block T-cell function
by targeting:
− Cytotoxic-T-lymphocyte-associated protein 4 (CTLA-4)
− Programmed cell death protein 1 (PD-1)
− Combination therapies targeting the two checkpoints, CTLA-4 and PD-1
◦ Vaccines: administer vaccines to expand antigen-specific T cells
DC-based and viral-vector-based vaccines

Gut microbiota modulate cancer therapy
13
• Commensal microbes have a beneficial
role in the fight against cancer
• Gut microbiota composition is
dramatically impacted by common
anti-neoplastic drugs
• Gut microbiota contributes to the efficacy
of cancer therapies with chemotherapy
drugs, T cell transfers and immune
checkpoint blockers
