CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]

, 2009
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Germinal center reactions in tertiary lymphoid structures associate with neoantigen burden, humoral immunity and long-term survivorship in pancreatic cancer

OncoImmunology, 2021
Pancreatic ductal adenocarcinoma (PDAC) has traditionally been thought of as an immunologically quiescent tumor type presumably because of a relatively low tumor mutational burden (TMB) and poor responses to checkpoint blockade therapy.

The role of T cell receptor dimerization for T cell antagonism and T cell specificity

Molecular Immunology, 1998
T cell responses are highly specific and T cell receptors (TCRs) can recognise subtle differences in major histocompatibility complex (MHC)-peptide complexes. While nominal peptide antigens usually act as full agonists that trigger the whole spectrum of T cell responses, some peptides exhibiting mutations at the TCR-MHC/peptide contact site stimulate ...

Role of regulatory T cells in immune tolerance [PDF]

, 2009
In this present work, we investigated the role of dendritic cells (DC) and regulatory T cells (Treg) in immune tolerance as well as their potential in the treatment of autoimmune or graft versus host (GvH) diseases.

Protocol for engineering binding domains to recognize ligand-bound receptors by using yeast surface display

STAR Protocols
Summary: Yeast surface display is a versatile protein engineering technology, enabling precise control of the applied selection pressure. We present a yeast-surface-display-based protocol for the enrichment of binders specifically recognizing ligand ...

Pre-treatment tumor neo-antigen responses in draining lymph nodes are infrequent but predict checkpoint blockade therapy outcome

OncoImmunology, 2020
Immune checkpoint blockade (ICPB) is a powerfully effective cancer therapy in some patients. Tumor neo-antigens are likely main targets for attack but it is not clear which and how many tumor mutations in individual cancers are actually antigenic, with ...

T Cell Hybrids with T Cell Functions

, 1979
Different T cell functions, e.g. help, suppression and cytotoxicity are associated with different T cell subsets, bearing distinctive differentiation markers. Thus effector T cells mediating help are Ly 1+2−3− and may bear Ia determinants, those mediating suppression are Ly 1−2+3+, IJ+, and cytotoxic cells are Ly 1−2+3+ and do not bear Ia determinants (

T-cell based immunotherapies for Parkinson’s disease

Exploration of Neuroprotective Therapy, 2021
Current evidence indicates that neurodegeneration of dopaminergic neurons of the substantia nigra associated to Parkinson’s disease is a consequence of a neuroinflammatory process in which microglial cells play a central role.

The role of ICOS in the development of CD4 T cell help and the reactivation of memory T cells [PDF]

, 2007
We have addressed the role of the inducible costimulator (ICOS) in the development of T cell help for B cells and in the generation, survival and reactivation of memory CD4 T cells and B cells.

Metabolic regulation of immune responses to cancer

Cancer Biology & Medicine, 2022
The tumor microenvironment is an ecosystem composed of multiple types of cells, such as tumor cells, immune cells, and cancer-associated fibroblasts. Cancer cells grow faster than non-cancerous cells and consume larger amounts of nutrients.
