 \chapter{introduction}
 
+T cell-based immunotherapies have received great interest from clinicians and
+industry due to their potential to treat, and often cure, cancer and other
+diseases\cite{Fesnak2016,Rosenberg2015}. In 2017, Novartis and Kite Pharma
+received FDA approval for \textit{Kymriah} and \textit{Yescarta} respectively,
+two genetically-modified \gls{car} T cell therapies against B cell malignancies.
+Despite these successes, \gls{car} T cell therapies are constrained by an
+expensive and difficult-to-scale manufacturing process with little control on
+cell quality and phenotype3,4. State-of-the-art T cell manufacturing techniques
+focus on anti-CD3 and anti-CD28 activation and expansion, typically presented on
+superparamagnetic, iron-based microbeads (Invitrogen Dynabead, Miltenyi MACS
+beads), on nanobeads (Miltenyi TransACT), or in soluble tetramers
+(Expamer)\cite{Roddie2019,Dwarshuis2017,Wang2016, Piscopo2017, Bashour2015}.
+These strategies overlook many of the signaling components present in the
+secondary lymphoid organs where T cells expand in vivo. Typically, T cells are
+activated under close cell-cell contact, which allows for efficient
+autocrine/paracrine signaling via growth-stimulating cytokines such as
+\gls{il2}. Additionally, the lymphoid tissues are comprised of \gls{ecm}
+components such as collagen, which provide signals to upregulate proliferation,
+cytokine production, and pro-survival pathways\cite{Gendron2003, Ohtani2008,
+  Boisvert2007, Ben-Horin2004}. We hypothesized that culture conditions that
+better mimic these in vivo expansion conditions of T cells, can significantly
+improve the quality and quantity of manufactured T cells and provide better
+control on the resulting T cell phenotype.
+
+% TODO mention the Cloudz stuff that's in my presentation
+
+A variety of solutions have been proposed to make the T cell expansion process
+more physiological. One strategy is to use modified feeder cell cultures to
+provide activation signals similar to those of \glspl{dc}\cite{Forget2014}.
+While this has the theoretical capacity to mimic many components of the lymph
+node, it is hard to reproduce on a large scale due to the complexity and
+inherent variability of using cell lines in a fully \gls{gmp}-compliant manner.
+Others have proposed biomaterials-based solutions to circumvent this problem,
+including lipid-coated microrods\cite{Cheung2018}, 3D-scaffolds via either
+Matrigel\cite{Rio2018} or 3d-printed lattices\cite{Delalat2017}, ellipsoid
+beads\cite{meyer15_immun}, and \gls{mab}-conjugated \gls{pdms}
+beads\cite{Lambert2017} that respectively recapitulate the cellular membrane,
+large interfacial contact area, 3D-structure, or soft surfaces T cells normally
+experience in vivo. While these have been shown to provide superior expansion
+compared to traditional microbeads, none of these methods has been able to show
+preferential expansion of functional naïve/memory and CD4 T cell populations.
+Generally, T cells with a lower differentiation state such as naïve and memory
+cells have been shown to provide superior anti-tumor potency, presumably due to
+their higher potential to replicate, migrate, and engraft, leading to a
+long-term, durable response\cite{Xu2014, Fraietta2018, Gattinoni2011,
+  Gattinoni2012}. Likewise, CD4 T cells are similarly important to anti-tumor
+potency due to their cytokine release properties and ability to resist
+exhaustion\cite{Wang2018, Yang2017}. Therefore, methods to increase naïve/memory
+and CD4 T cells in the final product are needed, a critical consideration being
+ease of translation to industry and ability to interface with scalable systems
+such as bioreactors.
+
+% TODO probably need to address some of the modeling stuff here as well
+
+This thesis describes a novel degradable microscaffold-based method derived from
+porous microcarriers functionalized with anti-CD3 and anti-CD28 \glspl{mab} for
+use in T cell expansion cultures. Microcarriers have historically been used
+throughout the bioprocess industry for adherent cultures such as stem cells and
+\gls{cho} cells, but not with suspension cells such as T
+cells\cite{Heathman2015, Sart2011}. The microcarriers chosen to make the DMSs in
+this study have a microporous structure that allows T cells to grow inside and
+along the surface, providing ample cell-cell contact for enhanced autocrine and
+paracrine signaling. Furthermore, the carriers are composed of gelatin, which is
+a collagen derivative and therefore has adhesion domains that are also present
+within the lymph nodes. Finally, the 3D surface of the carriers provides a
+larger contact area for T cells to interact with the \glspl{mab} relative to
+beads; this may better emulate the large contact surface area that occurs
+between T cells and \glspl{dc}. These microcarriers are readily available in
+over 30 countries and are used in an FDA fast-track-approved combination retinal
+pigment epithelial cell product (Spheramine, Titan Pharmaceuticals) {\#}[Purcell
+documentation]. This regulatory history will aid in clinical translation. We
+show that compared to traditional microbeads, \gls{dms}-expanded T cells not
+only provide superior expansion, but consistently provide a higher frequency of
+naïve/memory and CD4 T cells (CCR7+CD62L+) across multiple donors. We also
+demonstrate functional cytotoxicity using a CD19 \gls{car} and a superior
+performance, even at a lower \gls{car} T cell dose, of \gls{dms}-expanded
+\gls{car}-T cells in vivo in a mouse xenograft model of human B cell \gls{all}.
+Our results indicate that \glspl{dms} provide a robust and scalable platform for
+manufacturing therapeutic T cells with higher naïve/memory phenotype and more
+balanced CD4+ T cell content.
