TLDR
Atopic asthma is associated with activation in the bronchi of the interleukin-3, 4, and 5 and GM-CSF gene cluster, a pattern compatible with predominant activation of the TH2-like T-cell population.Abstract:
Background. In atopic asthma, activated T helper lymphocytes are present in bronchial-biopsy specimens and bronchoalveolar-lavage (BAL) fluid, and their production of cytokines may be important in the pathogenesis of this disorder. Different patterns of cytokine release are characteristic of certain subgroups of T helper cells, termed TH1 and TH2, the former mediating delayed-type hypersensitivity and the latter mediating IgE synthesis and eosinophilia. The pattern of cytokine production in atopic asthma is unknown. Methods. We assessed cells obtained by BAL in subjects with mild atopic asthma and in normal control subjects for the expression of messenger RNA (mRNA) for interleukin-2, 3, 4, and 5, granulocytemacrophage colony-stimulating factor (GM-CSF), and interferon gamma by in situ hybridization with 32P-labeled complementary RNA. Localization of mRNA to BAL T cells was assessed by simultaneous in situ hybridization and immunofluorescence and by in situ hybridization after immunomagnetic enrichment or...read more

TH1 and TH2 cells: different patterns of lymphokine secretion lead to different functional properties.

TL;DR: Two types of cloned helper T cells are described, defined primarily by differences in the pattern of lymphokines ynthesized, and the different functions of the two types of cells and their lymphokine synthesis are discussed.

TL;DR: A panel of antigen-specific mouse helper T cell clones was characterized according to patterns of lymphokine activity production, and two types of T cell were distinguished.

IL-4 directs the development of Th2-like helper effectors.
TL;DR: The concept that different subsets of helper cells, which correspond roughly to Th1 and Th2 subsets, can develop rapidly in short term culture with respectively low vs high levels of IL-4 support the concept that such distinct phenotypes arise from alternate pathways of differentiation.

TL;DR: The predicted protein sequence shows extensive homology with an uncharacterized open reading frame, BCRFI, in the Epstein-Barr virus genome, suggesting the possibility that this herpes virus exploits the biological activity of a captured cytokine gene to enhance its survival in the host.

TL;DR: It is shown that cross-linkage of FcεRI on a series of non-transformed murine mast cell lines, or treatment of these cells with calcium ionophores, stimulates increased messenger RNA levels and secretion of a group of lymphokines classically produced by a subset of murine T cell lines (TH2cells).
