In the above video, what type of signaling is the IL-2 signal that causes the T-cell to make more copies of itself? Juxtacrine, paracrine, endocrine, or autocrine?
The initial binding of the antigen to the T-Cell Receptor (TCR) isp- A juxtacrine signaling, B autocrine signaling, C endocrine, D paracrine?
What type of signal is the IP3 molecule within the cell? Juxtacrine ligand, paracrine ligand, second messenger, or protein kinase?
Explanation / Answer
IP3 molecule act as an secondary messenger inside the cell. IP3 molecule functions to transfer the chemical message recieved by the cell from hormones,neurotransmitters,growth factors etc.
Autocrine helps the T-cell to make more number of copeis. Regeneration and cell division main function.
Paracrine signalling helps in the initial binding of antigen to the T-cell Receptor.
