Immune networks: multi-tasking capabilities near saturation [PDF]

Journal of Physics A 46, 415003 (2013). (IOP Select: Highlights-2013), 2013
Pattern-diluted associative networks were introduced recently as models for the immune system, with nodes representing T-lymphocytes and stored patterns representing signalling protocols between T- and B-lymphocytes. It was shown earlier that in the regime of extreme pattern dilution, a system with $N_T$ T-lymphocytes can manage a number $N_B!=!\order ...

Functional exhaustion of CD4⁺T cells in HIV/HCV coinfected HAART-treated patients

Медицинская иммунология, 2023
Infection with hepatitis C virus (HCV) is common among HIV-positive patients, with up to 50% of them being coinfected in Russia. While highly active antiretroviral therapy (HAART) suppresses HIV replication and restores the immune system of HIV-infected ...

Induction of secreted human immunodeficiency virus type 1 (HIV-1) resistance factors in CD4-positive T lymphocytes by attenuated HIV-1 infection.

Virology, 2002
This report describes induction of HIV-1 resistance and synthesis of resistance factors in immortal CD4-positive T lymphocytes. SupT1 cells were infected by NL4-3 attenuated by a defect in the vif gene through coculture with infected primary lymphocytes.

Inferring HIV escape rates from multi-locus genotype data [PDF]

Front. Immunol. 4:252. 2013, 2013
Cytotoxic T-lymphocytes (CTLs) recognize viral protein fragments displayed by major histocompatibility complex (MHC) molecules on the surface of virally infected cells and generate an anti-viral response that can kill the infected cells. Virus variants whose protein fragments are not efficiently presented on infected cells or whose fragments are ...

High incidence of activating STAT5B mutations in CD4-positive T-cell large granular lymphocyte leukemia [PDF]

Blood, 2016
To the editor: Large granular lymphocyte (LGL) leukemia is a group of chronic lymphoproliferative disorders of cytotoxic T or natural killer (NK) cells frequently complicated with cytopenia and autoimmune phenomena.[1][1],[2][2] In the current World Health Organization (WHO) classification, T ...

Early changes of CD4-positive lymphocytes and NK cells in patients with severe Gram-negative sepsis [PDF]

Critical Care, 2006
Abstract Introduction Our aim was to define early changes of lymphocytes and of NK cells in severe sepsis and to correlate them with serum levels of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1).

Evaluation of the relation between T-Lymphocytes (CD4 + ve and CD8 + ve) and pemphigus vulgaris pathogenesis and severity

Indian Journal of Dermatopathology and Diagnostic Dermatology, 2019
Background: Pemphigus vulgaris (PV) is an autoimmune bullous disease involving both the skin and mucus membranes. Infiltrating CD4+ and CD8+ T-lymphocytes may have a vital role in its pathogenesis.

Regulatory T cells in children with recently diagnosed type 1 diabetes

Indian Journal of Endocrinology and Metabolism, 2012
Background: Regulatory T cells have an important role in the control of immune reactivity against self antigens and probably play a role in pathogenesis of type 1 diabetes (T1D).
