The SARS-CoV-2 virus can enter the cells using S1 viral spike (S) protein, not only by binding to ACE2, but also through other cellular receptors. These candidate receptors include CD46, which, like CD45, belongs pan-leukocyte and is expressed on all types of lymphocytes. In turn, infection accompanied damage almost compartments immune system, mainly T purpose study was evaluate expression leve...

CD8(+) cytotoxic T lymphocytes (CTLs) recognize antigen in the context of major histocompatibility complex (MHC) class I molecules. Class I epitopes have been classified as dominant or subdominant depending on the magnitude of the CTL response to the epitope. In this report, we have examined the in vitro memory CTL response of H-2(d) haplotype murine CD8(+) T lymphocytes specific for a dominant...

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. Because systemic inflammation is also a component of emphysema, we hypothesize that peripheral CD8+ T lymphocytes of emphysematous smokers who show evidence of systemic inflammation will h...

PURPOSE The expression of FasR, Fas-L and Bcl-2 on CD4+ and CD8+ T lymphocytes subpopulations from the cord blood were assayed. The results in blood from boys and girls were analyses separately and compared. MATERIAL AND METHODS Twenty four full-term newborns: 13 females and 11 males were included into the study. Blood from the umbilical vein was collected immediately after cutting the umbili...

In human cutaneous leishmaniasis (CL), the immune response is mainly mediated by T-cells. The role of CD8+ T-lymphocytes, which are related to healing or deleterious functions, in affecting clinical outcome is controversial. The aim of this study was to evaluate T-cell receptor diversity in late-differentiated effector (LDE) and memory CD8+ T-cell subsets in order to create a profile of specifi...

CD8 1 cytotoxic T lymphocytes (CTLs) recognize antigen in the context of major histocompatibility complex (MHC) class I molecules. Class I epitopes have been classified as dominant or subdominant depending on the magnitude of the CTL response to the epitope. In this report, we have examined the in vitro memory CTL response of H-2 d haplotype murine CD8 1 T lymphocytes specific for a dominant an...

In contrast to the effects of cigarette smoke on T-lymphocyte subsets in the airways, it has not yet been determined whether smoking has immunomodulatory effects on surface antigens of peripheral blood T-lymphocytes and, if that is the case, whether these effects differ in smokers with and without chronic obstructive pulmonary disease (COPD). The present authors have, therefore, examined the ex...

It is believed that CD8+ T lymphocytes or Abs can independently clear many primary viral infections, including those caused by Orthopoxviruses (OPV), a genus that includes the human pathogens variola and monkeypox and the vaccine species vaccinia virus. However, most experiments addressing the role of Abs and CD8+ T cells in protection have used viruses that are not specific for the host. In th...

BACKGROUND Altered immunoresponse is associated with tumorigenesis and cancer progression. This study assessed the levels of tumor-infiltrating CD3 + or CD8 + T lymphocytes and interleukin-2 (IL-2) protein in radically resected non-small cell lung cancer (NSCLC) tissues to predict overall survival (OS) of the patients. METHODS Paraffin-embedded tissue specimens from 129 NSCLC patients were re...
