CD8+ CD28− and CD8+ CD57+ T cells and their role in health and disease
Chronic antigenic stimulation leads to gradual accumulation of late-differentiated, antigen-specific, oligoclonal T cells, particularly within the CD8(+) T-cell compartment. They are characterized by critically shortened telomeres, loss of CD28 and/or gain of CD57 expression and are defined as either CD8(+) CD28(-) or CD8(+) CD57(+) T lymphocytes ...

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

Inflaming the CD8+ T Cell Response [PDF]
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.

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

Distribution of melanocytes in the skin of psoriasis patients
Psoriasis is a chronic immune-mediated inflammatory disease with predominant damage to the skin and joints. Despite fundamental studies of its pathogenesis, the cause of the development of the T-cell response has not been determined. More recently, a new

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.

Imaging the Effector CD8 Synapse [PDF]
Here, we describe 4D imaging of effector CD8+ T cells as they conjugate and kill live targets in vitro and analyze the polarization dynamics of intracellular compartments to this cell-cell interface.

Defining Memory CD8 T Cell [PDF]
CD8 T cells comprising the memory pool display considerable heterogeneity, with individual cells differing in phenotype and function. This review will focus on our current understanding of heterogeneity within the antigen-specific memory CD8 T cell compartment and classifications of memory CD8 T cell subsets with defined and discrete functionalities ...

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.

Peripheral Tolerance of CD8 T Lymphocytes [PDF]
Whereas high-avidity recognition of peptide-MHC complexes by developing T cells in the thymus results in deletion and promotes self-tolerance, such recognition by mature T cells in the periphery results in activation and clonal expansion. This dichotomy represents the basis of a dilemma that has stumped immunologists for many years, how are self ...
