Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University In the troposphere, ozone is naturally formed when sunlight splits nitrogen dioxide (NO2): NO2 + sunlight → NO + O O + O2 → O3 Ozone (O3) can go on to react with nitric oxide (NO) to form nitrogen dioxide (NO2) and oxygen: NO + O3 → NO2 + O2 This results in no net gain of ozone (O3). However, with the anthropogenic production of ozone forming precursors (NO, NO2, and volatile organic compounds) through the combustion...

Given the limited xenograft models available to study interactions between human CART and myeloid cells, we established in vitro and in vivo models to understand the impacts of human macrophages on CART cells. Findings can potentially be generalized to evaluate macrophage roles in the tumor microenvironment and test macrophage-targeted immunotherapies.

FAQs
Persistent antigen exposure drives coordinated changes rather than a single loss of function. T cells undergo altered transcriptional programs, metabolism, cytokine production, and proliferative capacity, which together constrain their ability to sustain immune control. Examining these linked features helps researchers distinguish exhaustion-related dysfunction from isolated changes in one cellular activity.
PD-1, TIM-3, and LAG-3 serve as inhibitory receptor features associated with exhausted T cells. Their increased expression provides useful evidence when researchers characterize exhaustion states, but receptor patterns should be interpreted alongside functional, transcriptional, metabolic, and proliferative changes. This broader assessment supports more precise analysis of immune dysfunction in tumors.
Stem-like T cell populations are important because they may retain characteristics relevant to maintaining or renewing antitumor responses within an exhausted system. Identifying these populations gives cancer researchers a way to examine functional differences among exhausted cells, rather than treating all exhaustion states as equivalent. That distinction may guide treatment design and improve response durability.
Researchers can define exhaustion states by integrating several dimensions of T cell behavior and biology. Useful considerations include inhibitory receptor expression, cytokine production, proliferation, transcriptional programs, and metabolism, together with the presence of functional or stem-like populations. This multidimensional approach can reveal meaningful variation among tumor-associated T cells and support more informative patient stratification.
Studying exhausted T cells helps explain how tumors limit effective immune attack and identifies inhibitory features that can be targeted therapeutically. These findings support the development of checkpoint inhibitors, which are designed within a broader effort to address inhibitory signaling and restore more effective antitumor responses. The resulting knowledge also informs combination treatment strategies.
Engineered T cell therapies are relevant when researchers seek to improve antitumor immune activity in the setting of dysfunctional or exhausted responses. Their development is informed by understanding how persistent stimulation affects transcription, metabolism, cytokine production, and proliferation. Comparing these properties with functional and stem-like populations can help shape treatment design and the goal of durable tumor control.
Characterizing exhaustion states may improve patient stratification by revealing differences in inhibitory receptor expression, cellular function, and the presence of stem-like T cell populations. Those distinctions can help researchers design more suitable checkpoint inhibitor, engineered-cell, or combination approaches. In turn, better alignment between tumor immune features and treatment strategy may support more durable antitumor responses.
