SnapShot: Cytokines IV

Receptor tyrosine kinases Diverse tissue DCs, other myeloid cells Differentiation and proliferation; synergizes with stem cell factor ↓ = impaired hematopoietic stem cell repopulation and B cell precursors G-CSF GCSFR dimer Macrophages, fibroblasts, other tissues Committed progenitors Differentiation and activation of granulocytes ↓ = neutropenia

SnapShot: Cytokines II

SnapShot: Cytokines III

Inflammatory; promotes activation and production of acute-phase proteins ↓ = disregulated fever; increased susceptibility to bacterial infection; enhanced resistance to LPS-induced septic shock ↑ = exacerbation of arthritis and colitis T cells, B cells Many cell types Promotes activation and cytotoxicity; development of lymph nodes and Peyer's patches ↓ = defective response to bacterial pathoge...
