• The cause of selective IgM deficiency remains unclear, although various mechanisms have been proposed, such as an increase in regulatory T cell functions, defective T helper cell functions and impaired terminal differentiation of B lymphocytes into IgM-secreting cells among others.
• Human immunodeficiency virus (HIV) binds CD4 and a chemokine receptor on the surface of a T helper cell to gain entry.
• Priming is the first contact that antigen-specific T helper cell precursors have with an antigen.
• Others have shown that treatment with PD-L2 Ig led to T helper cell proliferation.
• This occurs when a naïve T helper cell recognizes antigen and needs to migrate to the follicle as a T follicular helper cell (TFH cell).

• . It presents fragments from it to T cells. The upper, Th0, is a T helper cell. The fragment is presented to it by MHC2.
• After the processed antigen (peptide) is complexed to the MHC molecule, they both migrate together to the cell membrane, where they are exhibited (elaborated) as a complex that can be recognized by the CD 4+ (T helper cell) – a type of white blood cell.
• Eosinophilic folliculitis associated with HIV infection typically affects individuals with advanced HIV and low T helper cell counts.
• Spontaneous regression is common in these tumors, and it is mediated by infiltration of CD8-expressing T cells followed by expression of Type 1 T helper cell cytokines (such as Interferon-gamma) and recruitment of antitumour effector cells.
• Immunohistology profile have shown cells consistent with a delayed hypersensitivity with T helper cell infiltrates, dendritic cells and epidermal Langerhans cells.

• The first IL-1 receptor-associated kinase (IRAK) was observed in 1994 through experiments with murine T helper cell lines D10N and EL-4.
• A high level of secretory IgA results from the interaction of B cells and intestinal antigen presenting dendritic cell (DC) in cooperation with follicular T helper cell (Tfh) in the germinal centers (GCs) of Peyer´s patches.
• The APC then travels to a lymph node, where it presents the displayed allergen to a CD4+ T-cell, or T-helper cell.
• Increasingly, there is strong evidence from mouse and human-based scientific studies of a broader diversity in CD4+ effector T helper cell subsets.
• For example, helminth infections cause potent and highly polarized immune response characterized by increased T-helper cell type 2 (Th2) cytokine and Immunoglobulin E (IgE) production.

• It is essentially a T helper cell driven reaction, recruited by dendritic cells.
• It has been shown to modulate the expression of Interleukin-6 (IL-6) and affect the balance of T helper cell cytokines.
• Mature T helper cells upregulate EBI2 to follow the oxysterol gradient, migrating to the outer edges of the T cell zone to receive signals from antigen-presenting dendritic cells arriving from the tissues.
• When stimulated by CD80, T helper cells preferentially differentiate into Th1 cells.
