5 Questions
What is the role of cytokine receptors?
Cytokine receptors are responsible for signal transduction initiated by cytokine binding, which activates JAK (Janus kinase) and leads to phosphorylation of tyrosine. This phosphorylation allows for the binding of STAT (Signal transducers and activators of transcription), which then translocates to the cell's DNA and initiates transcription of specific target genes.
What are the unique high affinity subunits of cytokine receptors?
Cytokine receptors have unique high affinity subunits that are associated with the activation of the target cell.
What is the role of SCF in hematopoiesis?
SCF (Stem cell factor) plays a role in hematopoiesis, which is the process of blood cell formation.
Which cytokine is involved in the innate immune response and causes fever and capillary effects?
IL-1 (Interleukin 1) is involved in the innate immune response and can cause fever and capillary effects.
Which cytokine is involved in the adaptive immune response via B cells?
IL-6 (Interleukin 6) is involved in the adaptive immune response via B cells.
