Immune alterations in vestibular neuritis: a retrospective database pilot study on T and B lymphocyte profiles and cytokine levels [PDF]

Frontiers in Neurology
BackgroundVestibular neuritis (VN) etiology remains elusive, with hypotheses suggesting viral infection, non-infectious inflammation, or immune responses.

Heterogeneity of helper/inducer T lymphocytes. I. Lymphokine production and lymphokine responsiveness. [PDF]

The Journal of experimental medicine, 1987
Antigen-specific, Ia-restricted helper/inducer T lymphocytes consist of subsets that can be distinguished by lymphokine secretion. One, called Th1, secretes IL-2 and the other, termed Th2, produces BSF-1/IL-4 in response to stimulation by lectin or antigen receptor signals, and each uses the respective lymphokine as its autocrine growth factor.

Clearance of Giardia muris infection requires helper/inducer T lymphocytes. [PDF]

The Journal of experimental medicine, 1987
The aim of this work was to identify the T cell subset (helper/inducer or cytotoxic/suppressor) that plays a major part in the clearance of Giardia muris infection. BALB/c mice were selectively depleted of helper/inducer (Th/i) or cytotoxic/suppressor (Tc/s) T cells, by treatment with rat IgG monoclonal antibodies directed against the Th/i cell surface

Transfusions enriched for W3/25+ helper/inducer T lymphocytes prevent spontaneous diabetes in the BB/W rat [PDF]

Diabetologia, 1987
Transfusions of spleen cells are known to prevent spontaneous autoimmune diabetes in susceptible BB/W rats, while T cell-depleted transfusions are ineffective. To characterize further the protective cell(s), we transfused young diabetes prone rats with splenocytes from diabetes resistant BB/W rats that were treated in vitro to enrich them in either OX8+

Heterogeneity of helper/inducer T lymphocytes. II. Effects of interleukin 4- and interleukin 2-producing T cell clones on resting B lymphocytes. [PDF]

The Journal of experimental medicine, 1988
To compare the helper function of murine T cell clones that secrete IL-2 and IFN-gamma (Th1 cells) or IL-4 and IL-5 (Th2), purified resting B cells were stimulated with F(ab')2 rabbit anti-mouse Ig (RAMG) and rabbit Ig-specific, class II MHC-restricted cloned T cells belonging to the two subsets.

Development of Human ILCs and Impact of Unconventional Cytotoxic Subsets in the Pathophysiology of Inflammatory Diseases and Cancer

Frontiers in Immunology, 2022
Innate lymphoid cells (ILCs) were firstly described by different independent laboratories in 2008 as tissue-resident innate lymphocytes mirroring the phenotype and function of T helper cells. ILCs have been subdivided into three distinct subgroups, ILC1,

Immunological alterations in patients with primary tumors in central nervous system [PDF]

Arquivos de Neuro-Psiquiatria, 1999
Natural killer (NK) cells play an important role in immune surveillance against tumors. The present work aimed to study the cytotoxic activity of NK cells and T cell subsets in peripheral blood of 13 patients with primary tumors in central nervous system

Helper-Inducer T-Lymphocytes Mediate Diabetes in EMC-Infected BALB/c By J Mice [PDF]

Diabetes, 1987
Diabetes mellitus developing in BALB/c ByJ mice infected with the M variant of encephalomyocarditis (EMC) virus is dependent on thymic immune mechanisms. We treated mice with the anti-Tlymphocyte monoclonal anti-L3T4 and anti-Lyt2.2 antibodies before virus inoculation and monitored the infection and occurrence of diabetes thereafter.
