Studying Interactions between Myeloid Cells and CAR T Cells In Vitro and In Vivo

2025
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.

A simple, efficient and robust way to synchronize the delivery of multiple viral components to plant cells via Agrobacterium-mediated transient expression is described. This approach is amenable for studying replication, encapsidation followed by in vitro reassembly of non-viral components into genome depleted optical viral ghosts suitable for biomedical applications.

To study the interaction of bacteria with the blood vessels under shear stress, a flow chamber and an in vivo mesenteric intravital microscopy model are described that allow to dissect the bacterial and host factors contributing to vascular adhesion.
FAQs
Their value comes from linking controlled observations to physiological complexity. An in vitro result can reveal how a selected cell type responds to a pathogen or treatment under defined medium and exposure conditions. An in vivo follow-up then tests whether that response remains evident when immune cells, tissues, organs, and systemic responses interact, strengthening interpretation of host-pathogen findings.
Cell type, culture medium, pathogen exposure, and treatment conditions directly shape what an experiment measures. Changing any of these variables can alter the observed interaction between host cells, pathogens, and candidate treatments. Explicit control and documentation make results easier to interpret and help investigators judge whether a finding should be examined in an intact host.
A simplified system does not reproduce all interactions present in a living organism. Immune cells may encounter different tissues, organs, and systemic signals in vivo, changing the response to infection or treatment. Consequently, an in vitro mechanism can be informative without being sufficient evidence of physiological relevance; in vivo testing addresses whether the observation persists in that broader setting.
A practical workflow is to use controlled experiments to investigate a defined host-pathogen or treatment question, then assess the relevant finding in a living host. The first stage can isolate responses under specified cell, medium, exposure, and treatment conditions; the second examines whether those observations remain meaningful amid interacting immune cells, tissues, organs, and systemic responses.
Together, these approaches can characterize host-pathogen interactions, identify immune mechanisms, and evaluate therapeutic candidates. The controlled setting helps link an outcome to selected experimental conditions, while the intact-host setting shows whether the response is retained in a more physiologically integrated context. Comparing the two therefore improves interpretation rather than treating either result as complete on its own.
In immunology and infection research, the combined evidence can inform the development of vaccines, diagnostics, and anti-infective treatments. In vitro findings may help investigators examine relevant responses under defined conditions, whereas in vivo results provide context from the intact host. Using both levels of evidence helps determine whether candidate effects have potential beyond the initial laboratory observation.
