Exploration and modulation of mechanical cues for enhanced cancer immunotherapy

The advent of immunotherapy, such as immune checkpoint blockade (ICB) and adoptive transfer of cytotoxic lymphocytes, has transformed the clinical care of cancer. However, a significant proportion of patients are resistant to immunotherapy or experience re ...

Stromal Notch ligands foster lymphopenia-driven functional plasticity and homeostatic proliferation of naive B cells

Freddy Radtke, Ute Koch

In lymphopenic environments, secondary lymphoid organs regulate the size of B and T cell compartments by supporting the homeostatic proliferation of mature lymphocytes. The molecular mechanisms underlying these responses and their functional consequences r ...

Tumor-specific cytolytic CD4 T cells mediate immunity against human cancer

Hatice Altug, Alexander Mathis, George Coukos, Xiaokang Li, Yen-Cheng Liu, David Gfeller, Pedro Romero, Alexandre Harari, Amélie Cachot, Margaux Saillard, Georg Alexander Rockinger

CD4 T cells have been implicated in cancer immunity for their helper functions. Moreover, their direct cytotoxic potential has been shown in some patients with cancer. Here, by mining single-cell RNA-seq datasets, we identified CD4 T cell clusters displayi ...

Fibronectin EDA and CpG synergize to enhance antigen-specific Th1 and cytotoxic responses

Jeffrey Alan Hubbell, Eleonora Simeoni, Melody Swartz, Alexandre de Titta, Alizée Jéléna Grimm, Ziad Julier

Subunit vaccines, employing purified protein antigens rather than intact pathogens, require the addition of adjuvants for enhanced immunogenicity with a correct balance between strong activation of the immune system and low toxicity. Here we show that the ...

MicroRNA Profile in CD8+T-Lymphocytes from HIV-Infected Individuals: Relationship with Antiviral Immune Response and Disease Progression

Evaristo Jose Planet Letschert

Background The relationship between host microRNAs (miRNA), viral control and immune response has not yet been elucidated in the field of HIV. The aim of this study was to assess the differential miRNA profile in CD8+ T-cells between HIV-infected individua ...

Conditional Deletion of Ferritin H in Mice Reduces B and T Lymphocyte Populations

Liviu Vanoaica, Maike Jaworski

The immune system and iron availability are intimately linked as appropriate iron supply is needed for cell proliferation, while excess iron, as observed in hemochromatosis, may reduce subsets of lymphocytes. We have tested the effects of a ferritin H gene ...

Tunable T cell immunity towards a protein antigen using polymersomes vs. solid-core nanoparticles

Jeffrey Alan Hubbell, Melody Swartz, Armando Stano, Karen Dane

Using poly(propylene sulfide) (PPS) and poly(ethylene glycol) (PEG) as components of a nanocarrier platform, we sought to compare immune responses induced by PPS-bl-PEG polymersomes (PSs; watery-core structures, with antigen incorporated within the PSs) an ...

Fast directed evolution of non-immunoglobulin proteins by somatic hypermutation in immune cells

Kai Johnsson, Christian Heinis

A review. New, improved phenotypes. Somatic hypermutation in immune cells can be used for the fast directed evolution of proteins other than Igs (e.g., autofluorescent proteins). The target gene is inserted into the genome of activated B lymphocytes where ...

CD8+ Cytotoxic T Lymphocyte Activation by Soluble Major Histocompatibility Complex-Peptide Dimers

Horst Vogel, Jean-Manuel Segura, Olivier Michielin, Bruno Meyer

CD8+ cytotoxic T lymphocyte (CTL) can recognize and kill target cells that express only a few cognate major histocompatibility complex class I-peptide (pMHC) complexes. To better understand the mol. basis of this sensitive recognition process, the authors ...
