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.

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

Induction of cytolytic T lymphocytes directed towards the V3 loop of the human immunodeficiency virus type 1 external glycoprotein gp120 by p55gag/V3 chimeric vaccinia viruses [PDF]

, 1993
T cell-mediated cytotoxicity may play an important role in controlling infection by human immunodeficiency virus (HIV). In order to study the ability of rationally designed antigens to induce cytolytic T lymphocytes (CTLs) we replaced stretches of 30 to ...

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 ...

Adoptive Immunotherapy in Chimeras with Donor Lymphocytes [PDF]

, 2003
Allogeneic stem cell transplantation has a well-defined indication in the treatment of hematological malignancies. The beneficial immune effect of allogeneic marrow transplantation has long been known, but only recently have methods been developed to ...

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 ...

Differential narrow focusing of immunodominant human immunodeficiency virus Gag-specific cytotoxic T-Lymphocyte responses in infected African and Caucasoid adults and children [PDF]

, 2000
Cytotoxic T-lymphocyte (CTL) activity plays a central role in control of viral replication and in determining outcome in cases of human immunodeficiency virus type 1 (HIV-1) infection.

Characterization of human cytomegalovirus peptide-specific CD8⁺ T-cell repertoire diversity following in vitro restimulation by antigen-pulsed dendritic cells [PDF]

, 2002
Under conditions of impaired T-cell immunity, human cytomegalovirus (HCMV) can reactivate from lifelong latency, resulting in potentially fatal disease.

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.
