Intratumoral CXCL13+CD8+T cell infiltration determines poor clinical outcomes and immunoevasive contexture in patients with clear cell renal cell carcinoma

Journal for ImmunoTherapy of Cancer, 2021
Background Chemokine (C-X-C motif) ligand 13 (CXCL13) was known as a selective chemotaxis for B cells, a product of follicular helper CD4+T cells (TFH) and a contributor to tertiary lymphoid structures (TLS).

Case Report: Early presentation of hereditary angioedema symptoms in a 2-year-old boy

Frontiers in Pediatrics
Hereditary angioedema (HAE) is a rare autosomal-dominant disease that is caused by a deficiency (type I) or dysfunction (type II) of the C1 inhibitor (C1-INH) due to a mutation in the SERPING1 gene, which codes for C1-INH.

Selection, transmission, and reversion of an antigen-processing cytotoxic T-lymphocyte escape mutation in Human Immunodeficiency Virus Type 1 infection [PDF]

, 2004
Numerous studies now support that human immunodeficiency virus type 1 (HIV-1) evolution is influenced by immune selection pressure, with population studies showing an association between specific HLA alleles and mutations within defined cytotoxic T ...

Brain Autoimmunity: The CD8 Question(s) [PDF]

Immunity, 2012
In this issue of Immunity, Na et al. (2012) show that the purging of central nervous system (CNS)-specific CD8(+) T cell repertoire requires direct contact with antigen expressing oligodendrocytes and inflammation tips the balance toward autoimmunity.

NK and T cells constitute two major, functionally distinct intestinal epithelial lymphocyte subsets in the chicken [PDF]

, 2001
Non-mammalian NK cells have not been characterized in detail; however, their analysis is essential for the understanding of the NK cell receptor phylogeny.

Inflaming the CD8+ T Cell Response [PDF]

Immunity, 2006
Although inflammatory cytokines induced by infection or vaccination with adjuvants have long been known to stimulate optimal antigen-presenting cell function, recent evidence indicates that some inflammatory cytokines also act directly on the responding T cells to control their response to infection.

Formation and phenotypic characterization of CD49a, CD49b and CD103 expressing CD8 T cell populations in human metastatic melanoma

OncoImmunology, 2018
Integrins α1β1 (CD49a), α2β1 (CD49b) and αEβ7 (CD103) mediate retention of lymphocytes in peripheral tissues, and their expression is upregulated on tumor infiltrating lymphocytes (TIL) compared to circulating lymphocytes.

Circulating activated lymphocyte subsets as potential blood biomarkers of cancer progression

Cancer Medicine, 2020
The objective of this study was to predict the value of lymphocyte subsets in cancer progression. Peripheral blood was obtained from 327 untreated patients with cancer and 158 healthy volunteers.

IL-12 and IL-4 activate a CD39-dependent intrinsic peripheral tolerance mechanism in CD8+ T cells [PDF]

, 2016
Immune responses to protein antigens involve CD4+ and CD8+ T cells, which follow distinct programs of differentiation. Naïve CD8 T cells rapidly develop cytotoxic T-cell (CTL) activity after T-cell receptor stimulation, and we have previously shown that ...

Dichotomy of two CD8+ lymphocyte subsets in HIV infection. Depletion of CD8+ CD3- and expansion of CD8+ CD3+ subsets: consequence on the CD4/CD8 ratio

Clinical and Experimental Immunology, 1991
SUMMARYIn order to highlight the underlying mechanism(s) of the CD8 lymphocyte expansion in the HIV infection, two distinct CD8 subsets were analysed: T CD8bright+ CD3+ with MHC-restricted activity, and non-T CD8dim+ CD3-, which performs natural killer (NK) activity.
