Modelling metastatic colonization of cholangiocarcinoma organoids in decellularized lung and lymph nodes

Gilles S. van Tienderen et al.

Summary: Cholangiocarcinoma (CCA) is an aggressive type of liver cancer that often metastasizes to the lungs and lymph nodes, resulting in poor patient outcomes. However, the mechanisms behind CCA metastasis are not well understood. In order to study the interactions between CCA tumor cells and the extracellular matrix (ECM) of metastatic sites, researchers created an in vitro model using patient-derived CCA organoids (CCAOs) combined with decellularized human lung and lymph node tissues. This model allowed for the investigation of how the ECM influences metastatic processes and provides new insights into cancer metastasis.

A synthetic human 3D in vitro lymphoid model enhancing B-cell survival and functional differentiation

Maaike V. J. Braham et al.

Summary: This study aimed to improve in vitro germinal center (GC) simulation by using 3D culture techniques. Human B-cells were incorporated into PEG-4MAL hydrogels, supported by CD40L cells, human tonsil-derived stromal cells, and cytokines. The 3D culture significantly increased plasmablast and plasma cell numbers, promoted antibody production, and enabled class switching of naive B-cells. Formation of large B-cell clusters resembling GC-like structures was also observed. In conclusion, this well-characterized and controllable hydrogel-based 3D lymphoid model supports enhanced B-cell survival, proliferation, differentiation, and antibody production.

The extracellular matrix and the immune system: A mutually dependent relationship

Tara E. Sutherland et al.

Summary: For decades, immunologists have focused on studying circulating immune cells, but recently there is a growing appreciation for the role of immune cells within the tissue microenvironment. However, the understanding of the extracellular matrix (ECM) and its interaction with the immune system remains limited. This review aims to explore the potential for biological discovery at the intersection of immunology and matrix biology.

New tools for immunologists: models of lymph node function from cells to tissues

Tochukwu Ozulumba et al.

Summary: The lymph node is a structured organ that plays a crucial role in the adaptive immune response. Various technologies have been used to explore its biology, from immunofluorescence to spatial biology techniques. However, new approaches are needed to study human immunity. This review presents different models and technologies for studying the lymph node, discusses challenges, and proposes future directions. It aims to benefit immunologists in expanding their toolkit for lymph node research.

Lymph node medulla regulates the spatiotemporal unfolding of resident dendritic cell networks

Milas Ugur et al.

Summary: This study discovered specific anatomical niches in lymph nodes where preDCs differentiate into immature cDCs. These niches, located in the medullary cords of the lymph nodes, play a role in the development of the cDC1 network. During inflammation, the network can be temporarily impaired, but can be restored by regulating the local density of cDC1s.

Summary: This study investigated the systemic toxicity and immune cell activation caused by metal exposure to oral mucosa using a multi-organ-on-chip approach. The results showed that metal exposure did not cause significant histological changes in gingiva and skin tissue, but did activate immune cells in the skin.

Modeling human adaptive immune responses with tonsil organoids

Lisa E. Wagar et al.

Summary: By utilizing human tonsils, researchers have developed a functional organotypic system that mimics key features of germinal centers in vitro, allowing for the study of humoral immune responses. This system not only enables a deeper understanding of critical mechanisms underlying adaptive immunity, but also facilitates rapid testing of vaccine candidates and adjuvants in an entirely human system.

Immunotherapy Goes Local: The Central Role of Lymph Nodes in Driving Tumor Infiltration and Efficacy

Kim M. van Pul et al.

Summary: Immune checkpoint blockade (ICB) has revolutionized oncology treatment, but resistance related to T cell deficiency and the importance of tumor-draining lymph nodes (TDLN) in overcoming this resistance have been overlooked. Targeting TDLN through therapeutic approaches involving DC activation may enhance ICB efficacy.

Immunomodulatory Scaffolds Derived from Lymph Node Extracellular Matrices

Yi Sun Choi et al.

Summary: Lymph node extracellular matrix (LNEM) can mimic lymph node microenvironments and enhance immunomodulatory effects, promoting M2 macrophage polarization and secretion of anti-inflammatory cytokines. In a 3D LNEM environment, macrophage phagocytic function is improved, showing potential for drug testing and tissue healing applications. LNEM hydrogel implantation facilitates macrophage recruitment and polarization towards M2 phenotype for tissue healing, indicating the utility of 3D immune system-mimicking biomaterials in tissue modeling and regenerative medicine.

Gremlin 1+ fibroblastic niche maintains dendritic cell homeostasis in lymphoid tissues

Varun N. Kapoor et al.

Summary: Fibroblastic reticular cells, specifically the Grem1(+) subset, play a crucial role in supporting T cell immunity and maintaining the homeostasis of tissue-resident cDCs in lymph nodes. Single-cell RNA sequencing analyses in both human and mouse lymph nodes reveal the significance of Grem1(+) FRCs in regulating lymphocyte compartmentalization and innate and adaptive immunity.

Acute Lymph Node Slices Are a Functional Model System to Study Immunity Ex Vivo

Maura C. Belanger et al.

Summary: Live murine lymph node tissue slices provide a versatile platform for studying immunity, maintaining spatial organization and cell populations while reflecting the 3D complexity of the organ. These slices show comparable viability and inflammatory response to cell suspensions, and exhibit stronger reactions to T cell receptor cross-linking in some cases. Additionally, they process protein antigens and respond to ex vivo challenge with antigen-specific cytokine secretion.
