Cytokine-armed dendritic cell progenitors for antigen-agnostic cancer immunotherapy

Dendritic cells (DCs) are specialized myeloid cells with the ability to uptake, process, and present antigens to T lymphocytes. They also generate cytokine and chemokine gradients that regulate immune cell trafficking, activation, and function. Monocyte-de ...

Direct In Vivo Activation of T Cells with Nanosized Immunofilaments Inhibits Tumor Growth and Metastasis

Bart Deplancke, Jorieke Weiden, Guido Van Mierlo

Adoptive T cell therapyhas successfully been implementedfor thetreatment of cancer. Nevertheless, ex vivo expansion of T cells byartificial antigen-presenting cells (aAPCs) remains cumbersome andcan compromise T cell functionality, thereby limiting their t ...

Unlocking Hidden Potential: Exploring the Complexities of Signaling in Immune Cell Activation to Optimize CAR Therapy

Mathieu Girardin

Chimeric antigen receptors (CARs) are synthetic, transmembrane proteins that trigger immune cell signaling following their engagement. They have been first utilized in T cells and later in natural killer (NK) cells to redirect their cytotoxicity toward a s ...

Mechanism of KRAS-driven T cell infiltration in colorectal cancer

Amber Dawn Bowler

Colorectal cancer is the second-leading cause of cancer death worldwide. Early-stage disease can be detected with preventative medical screening and is treatable with surgical resection. Sixty-percent of patients, however, are diagnosed with advanced-stage ...

Exploring the interplay of molecular pattern and valency for selective interactions at the bio-interface

Kaltrina Paloja

Cell-cell communication is fundamental for immune balance. Multivalent interactions of surface receptors at immune interfaces drive specific communication, with stimulatory and inhibitory signals guiding the immune outcome. Notably, the valency, affinity, ...

BCG hydrogel promotes CTSS-mediated antigen processing and presentation, thereby suppressing metastasis and prolonging survival in melanoma

Li Tang, Bing Feng, Thomas Gruber

Background The use of intralesional Mycobacterium bovis BCG (intralesional live BCG) for the treatment of metastatic melanoma resulted in regression of directly injected, and occasionally of distal lesions. However, intralesional-BCG is less effective in p ...

Protein Engineering for Personalized therapy and diagnosis

Lixia Wei

Protein Engineering, especially protein post-translational modification (PTM), ex-tends proteomes in a more complex way than one can expect from analysis of their encod-ing genomes. It can activate or deactivate certain catalytic functions, add new desired ...

Systematic analysis of biomolecular binding reactions using microfluidic systems

Amir Shahein

Transcription factor binding to a single binding site on DNA and its functional consequence in a promoter context are beginning to be relatively well understood. However, binding to clusters of sites has yet to be characterized in depth, and the functional ...

DNA-based biomaterials for nanoscale controlled modulation of immune cells

Alice Comberlato

Recent advances in the field of nanomaterials demonstrated how their use for vaccination can drastically improve immune responses, mainly by enhancing delivery and uptake of vaccine components. However, our understanding of the connections between presenta ...

The role of eosinophils in breast cancer

Luisa Spisak

Eosinophils are granulocytes and belong to the innate arm of immunity. Eosinophils can be in different basal or activation states and depending on which type of activation is applied, they exert different effector functions. These multi-functional cells ha ...

S-acylation by ZDHHC20 targets ORAI1 channels to lipid rafts for efficient Ca2+ signaling by Jurkat T cell receptors at the immune synapse

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Efficient immune responses require Ca2+ fluxes across ORAI1 channels during engagement of T cell receptors (TCR) at the immune synapse (IS) between T cells and antigen presenting cells. Here, we show that ZDHHC20-mediated S-acylation of the ORAI1 channel a ...

Enhancing T-cell response in cancer immunotherapy using nanoparticles

Cristiana Berti

Immunotherapy has been used in oncology in order to awaken the immune system of the patient against cancer. Within this promising field is emerging the use of therapeutic cancer vaccines, using tumor specific antigens to stimulate dendritic cells (DCs) ex ...

A Nanoscaffolded Spike-RBD Vaccine Provides Protection against SARS-CoV-2 with Minimal Anti-Scaffold Response

David Hacker, Florence Pojer, Bruno Emanuel Ferreira De Sousa Correia, Kelvin Ka Ching Lau

The response of the adaptive immune system is augmented by multimeric presentation of a specific antigen, resembling viral particles. Several vaccines have been designed based on natural or designed protein scaffolds, which exhibited a potent adaptive immu ...

Redox-Responsive Polycondensate Neoepitope for Enhanced Personalized Cancer Vaccine

Li Tang, Lixia Wei, Yu Zhao, Xiaomeng Hu

A versatile and highly effective platform remains a major challenge in the development of personalized cancer vaccines. Here, we devised a redox-responsive polycondensate neoepitope (PNE) through a reversible polycondensation reaction of peptide neoantigen ...

Myeloid Cells Orchestrate Systemic Immunosuppression, Impairing the Efficacy of Immunotherapy against HPV+ Cancers

Melody Swartz, Nadine Fournier, Douglas Hanahan, Stephan Wullschleger, Gabriele Galliverti, Mélanie Louise Tichet

Cancers induced by human papillomaviruses (HPV) should be responsive to immunotherapy by virtue of expressing the immunogenic oncoproteins E6/E7. However, advanced forms of cervical cancer, driven by HPV, are poorly responsive to immune response-enhancing ...

A computationally designed chimeric antigen receptor provides a small-molecule safety switch for T-cell therapy

George Coukos, Bruno Emanuel Ferreira De Sousa Correia, Jaume Bonet Martinez, Pablo Gainza Cirauqui, Sabrina Susan Vollers, Sailan Shui

The activity of CAR-T cells is reversibly halted with a small-molecule drug. Approaches to increase the activity of chimeric antigen receptor (CAR)-T cells against solid tumors may also increase the risk of toxicity and other side effects. To improve the s ...

Regulatory T cells engineered with TCR signaling-responsive IL-2 nanogels suppress alloimmunity in sites of antigen encounter

Na Li, Li Tang

Adoptive cell transfer of ex vivo expanded regulatory T cells (T-r(egs)) has shown immense potential in animal models of auto- and alloimmunity. However, the effective translation of such T-reg therapies to the clinic has been slow. Because T-reg homeostas ...
