LY-H as a potential screening biomarker for lymphocyte activation in peripheral blood [PDF]

Frontiers in Immunology
ObjectivesViral infections often cause morphological changes in peripheral blood lymphocytes. While the presence of reactive lymphocytes in blood smears reflects lymphocyte activation, their identification is often affected by morphological heterogeneity

Inherited immunodeficiencies associated with proximal and distal defects in T cell receptor signaling and co-signaling

Biomedical Journal, 2022
T lymphocytes are central cells of adaptive immunity. Activation of T lymphocytes by the antigen receptor of T cells (TCR) and co-stimulatory molecules involve specific signaling components and cascades.

Activation of lymphocytes [PDF]

Journal of Clinical Pathology, 1967
The technique involved in studying the activation of lymphocytes in the resting form, and their recognition as dividing and functional cells was studied, using phase contrast and agar as well as fluid culture. Standardization of technical methods was found to be essential, and the effect of variables was studied.

The Activation of Lymphocytes Is in Their CARMA [PDF]

Immunity, 2003
Lymphocyte activation via antigen receptors initiates adaptive immune responses. Two papers in this issue of Immunity demonstrate that CARMA-1, a CARD carrying member of the MAGUK family proteins, is essential for lymphocyte activation. CARMA-1 functions by coupling antigen receptor signals to NF-kappaB induction and JNK activation.

CTP Synthase 1 Is a Novel Therapeutic Target in Lymphoma

HemaSphere, 2023
Lymphoma is the most common hematological malignancy and is among the 10 most prevalent cancers worldwide. Although survival has been improved by modern immunochemotherapeutic regimens, there remains a significant need for novel targeted agents to treat ...

Reversal of splicing infidelity is a pre-activation step in B cell differentiation

Frontiers in Immunology, 2022
IntroductionB cell activation and differentiation is central to the adaptive immune response. Changes in exon usage can have major impacts on cellular signaling and differentiation but have not been systematically explored in differentiating B cells ...

Continuous Modeling of T CD4 Lymphocyte Activation and Function

Frontiers in Immunology, 2021
T CD4+ cells are central to the adaptive immune response against pathogens. Their activation is induced by the engagement of the T-cell receptor by antigens, and of co-stimulatory receptors by molecules also expressed on antigen presenting cells. Then, a

Alterations in immunophenotype and metabolic profile of mononuclear cells during follow up in children with multisystem inflammatory syndrome (MIS-C)

Frontiers in Immunology, 2023
IntroductionAlthough children seem to be less susceptible to COVID-19, some of them develop a rare but serious hyperinflammatory condition called multisystem inflammatory syndrome in children (MIS-C).
