Immunomodulator effect of Cnidoscolus aconitifolius leaves extract on CD4+ and CD8+ expression in Salmonella typhimurium-infected mice [PDF]

Pharmaciana
Typhoid fever is a common health problem in the community caused by Salmonella bacteria. The incidence rate of this infection will increase if a person’s immune system is weakened.

Priming of CD8+ T cell responses following immunization with heat-killed Plasmodium sporozoites. [PDF]

, 2006
Protective immune responses against malaria are induced by immunization with radiation-attenuated Plasmodium sporozoites. In contrast, non-viable, heat-killed sporozoites do not induce protection, emphasizing the requirement for live parasites to achieve

IL-4-secreting CD4+ T cells are crucial to the development of CD8+ T-cell responses against malaria liver stages. [PDF]

, 2002
CD4+ T cells are crucial to the development of CD8+ T cell responses against hepatocytes infected with malaria parasites. In the absence of CD4+ T cells, CD8+ T cells initiate a seemingly normal differentiation and proliferation during the first few days

CD8+ Lymphomatoid Papulosis [PDF]

Annals of Dermatology, 2011
Lymphomatoid papulosis (LyP) is defined as a histologically malignant, but clinically benign condition. It can appear as erythematous pink to purple papules or nodules. Immunophenotyping studies of the lymphomatoid papulosis lesions have shown a predominance of a CD4 expression and negativity for CD8.

Avidity of influenza-specific memory CD8+ T-cell populations decays over time compromising antiviral immunity [PDF]

, 2012
Decline of cell-mediated immunity is often attributed to decaying T-cell numbers and their distribution in peripheral organs. This study examined the hypothesis that qualitative as well as quantitative changes contribute to the declining efficacy of CD8+

Presence of tumor-infiltrating CD8+ T cells and macrophages correlates to longer overall survival in patients undergoing isolated hepatic perfusion for uveal melanoma liver metastasis

OncoImmunology, 2020
Uveal melanoma is a malignant tumor of the eye that often metastasizes to the liver conferring poor prognosis. When comparing immune profiles in peripheral blood of untreated patients with uveal melanoma liver metastasis and healthy blood donors, it was ...

Escaping high viral load exhaustion: CD8 cells with altered tetramer binding in chronic hepatitis B virus infection [PDF]

, 2002
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in

CD8+ and CD8- NKT Cells Exhibit Phenotypic Changes During Pregnancy

Immunological Investigations, 2022
NKT cell population is a relatively well-characterized immune cell subset. Numerous publications have characterized the phenotypical features of its subpopulations even in human pregnancy. Nevertheless, there have not been studies investigating the distribution of the NKT cells based on the surface presence of the CD8 receptor.

Early self-regulatory mechanisms control the magnitude of CD8+ T cell responses against liver stages of murine malaria. [PDF]

, 2003
Following immunization with Plasmodium yoelii sporozoites, the CD8(+) T cell population specific for the SYVPSAEQI epitope expressed in sporozoite and liver stages of this malaria parasite revealed the existence of a short term Ag presentation process ...
