Development of classical Hodgkin’s lymphoma in an adult with biallelic STXBP2 mutations

Haematologica, 2013
Experimental model systems have delineated an important role for cytotoxic lymphocytes in the immunosurveillance of cancer. In humans, perforin-deficiency has been associated with occurrence of hematologic malignancies.

Perforin, granzyme B, and FasL expression by peripheral blood T lymphocytes in emphysema

Respiratory Research, 2007
Background It is generally accepted that emphysematous lungs are characterized by an increase in the numbers of neutrophils, macrophages, and CD8+ T lymphocytes, the lasts having increased cytotoxic activity.

Killer cell proteases can target viral immediate-early proteins to control human cytomegalovirus infection in a noncytotoxic manner.

PLoS Pathogens, 2020
Human cytomegalovirus (HCMV) is the most frequent viral cause of congenital defects and can trigger devastating disease in immune-suppressed patients. Cytotoxic lymphocytes (CD8+ T cells and NK cells) control HCMV infection by releasing interferon-γ and ...

Dynamics of cytotoxic T–lymphocyte exhaustion [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1998
We examine simple mathematical models to investigate the circumstances under which the dynamics of cytotoxic T-lymphocyte (CTL) activation and differentiation may result in the loss of virus specific CD8+ cells, a process known as CTL exhaustion. We distinguish between two general classes of viruses: (i) viruses infecting cells that are not involved in

Cytotoxic T lymphocytes in regional lymph nodes in colon cancer

Acta Biomedica Scientifica
Background. The study of the subpopulation composition of cytotoxic T lymphocytes and the expression of co-inhibitory proteins on their surface in regional lymph nodes is necessary for the development of new methods of targeted therapy for colorectal ...

Cytotoxic Granule Exocytosis From Human Cytotoxic T Lymphocytes Is Mediated by VAMP7

Frontiers in Immunology, 2019
Cytotoxic T lymphocytes kill infected or malignant cells through the directed release of cytotoxic substances at the site of target cell contact, the immunological synapse.

GENERATION OF CYTOTOXIC T LYMPHOCYTES IN VITRO [PDF]

The Journal of Experimental Medicine, 1974
Mouse cytotoxic T lymphocytes (CTL) were generated in unidirectional mixed leukocyte cultures (MLC) using normal C57BL/6 spleen cells as responding cells and irradiated DBA/2 spleen cells as stimulating cells. Cytotoxicity was assayed on 51Cr-labeled P-815 (DBA/2) target cells, and the relative frequency of CTL in individual cell populations was ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Cytotoxic CD4+ T cells: origin, biological functions, diseases and therapeutic targets

Signal Transduction and Targeted Therapy
Cytotoxic CD4+ T lymphocytes are a unique subset of CD4+ T cells characterized by their cytokine secretion and cytolytic activity. Unlike traditional CD4+ helper T cells, cytotoxic CD4+ T lymphocytes exhibit similar cytotoxicity to that of CD8+ T cells ...
