Transforming growth factor beta 1 orTGF-β1 is a polypeptide member of thetransforming growth factor beta superfamily ofcytokines. It is a secreted protein that performs many cellular functions, including the control ofcell growth,cell proliferation,cell differentiation, andapoptosis. In humans, TGF-β1 is encoded by theTGFB1gene.[5][6]

Function

[edit]
See also:TGF beta signaling pathway

TGF-β is a multifunctional set of peptides that controlsproliferation,differentiation, and other functions in many cell types. TGF-β acts synergistically withtransforming growth factor-alpha (TGF-α) in inducingtransformation. It also acts as a negativeautocrinegrowth factor. Dysregulation of TGF-β activation and signaling may result inapoptosis. Many cells synthesize TGF-β and almost all of them have specific receptors for this peptide. TGF-β1,TGF-β2, andTGF-β3 all function through the same receptor signaling systems.[7]

TGF-β1 was first identified in humanplatelets as a protein with a molecular mass of 25kilodaltons with a potential role inwound healing.[8][9] It was later characterized as a largeprotein precursor (containing 390amino acids) that wasproteolytically processed to produce a mature peptide of 112 amino acids.[10]

TGF-β1 plays an important role in controlling theimmune system, and shows different activities on different types of cell, or cells at different developmental stages. Most immune cells (orleukocytes) secrete TGF-β1.[11]

T cells

[edit]

SomeT cells (e.g.regulatory T cells) release TGF-β1 to inhibit the actions of other T cells. Specifically, TGF-β1 prevents theinterleukin(IL)-1- &interleukin-2-dependentproliferation in activated T cells,[12][13] as well as the activation of quiescenthelper T cells andcytotoxic T cells.[14][15] Similarly, TGF-β1 can inhibit the secretion and activity of many othercytokines includinginterferon-γ,tumor necrosis factor-alpha (TNF-α), and variousinterleukins. It can also decrease the expression levels of cytokine receptors, such as theIL-2 receptor to down-regulate the activity of immune cells. However, TGF-β1 can alsoincrease the expression of certain cytokines in T cells and promote their proliferation,[16] particularly if the cells are immature.[11]

B cells

[edit]

TGF-β1 has similar effects onB cells that also vary according to thedifferentiation state of the cell. It inhibits proliferation, stimulatesapoptosis of B cells,[17] and controls the expression ofantibody,transferrin andMHC class II proteins on immature and mature B cells.[11][17]

Myeloid cells

[edit]

The effects of TGF-β1 onmacrophages andmonocytes are predominantly suppressive; this cytokine can inhibit the proliferation of these cells and prevent their production of reactive oxygen (e.g.superoxide (O2)) and nitrogen (e.g.nitric oxide (NO)) intermediates. However, as with other cell types, TGF-β1 can also have the opposite effect on cells of myeloid origin. For example, TGF-β1 acts as achemoattractant, directing an immune response to certainpathogens. Likewise, macrophages and monocytes respond to low levels of TGF-β1 in a chemotactic manner. Furthermore, the expression of monocytic cytokines (such asinterleukin(IL)-1α, IL-1β, andTNF-α),[15] and macrophage'sphagocytic can be increased by the action of TGF-β1.[11]

TGF-β1 reduces the efficacy of theMHC II inastrocytes anddendritic cells, which in turn decreases the activation of appropriatehelper T cell populations.[18][19]
