Characterization of T-cell receptor loci and expressed repertoire reveals a capacity for robust T-cell response in Atlantic cod (Gadus morhua)

Scientific Reports
The Atlantic cod presents a peculiar case in fish immunology, due to the loss of MHCII and CD4 genes. Despite the absent antibody response to T cell-dependent antigens, it is a prolific species.

Protocol for assessing T cell receptor-mediated human T cell cytotoxicity

STAR Protocols
Summary: Measuring the cytotoxicity of human T cells is a valuable but challenging task. We present a protocol for assessing the ability of polyclonal human T cells to kill target cells upon T cell receptor (TCR) triggering.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Glutamate receptor–T cell receptor signaling potentiates full CD8+ T cell activation and effector function in tumor immunity

iScience
Summary: Glutamate is best known as an excitatory neurotransmitter. However, its roles in T cell immunity remain underrecognized. We investigated the interplay between glutamate receptors (GluRs) and T cell receptors (TCRs) during CD8+ T cell activation.

Novel chimeric antigen receptor T cells based on T-cell receptor-like antibodies

Blood Science, 2019
. The need for novel therapeutics against human cancers such as leukemias and solid tumors is well recognized. Human T cells are poised to make a fundamental change in the therapeutic approach. T-cell interaction with a tumor cell is a critical event and

Transgenic expression of the Ly49A natural killer cell receptor confers class I major histocompatibility complex (MHC)-specific inhibition and prevents bone marrow allograft rejection. [PDF]

, 1996
Natural killer (NK) cells and some T cells are endowed with receptors specific for class I major histocompatibility complex (MHC) molecules that can inhibit cellular effector functions.

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

T-cell abnormalities are present at high frequencies in patients with hypereosinophilic syndrome

Haematologica, 2009
Background A T-cell clone, thought to be the source of eosinophilopoietic cytokines, identified by clonal rearrangement of the T-cell receptor and by the presence of aberrant T-cell immunophenotype in peripheral blood defines lymphocytic variant of ...
