Chapter 34.4, Problem 3RIA
Summary Introduction
CD4+ T cells and CD8+ T cells are two important T cells present in the human body. These cells are named because they contain cell-surface proteins that possess specific functions in the intercellular communications and are known as cluster of differentiation (CDs) molecules or immunogens or antigens. The cluster of differentiation (CDs) molecules are cell-surface proteins and most of them act as receptors. Each molecule of the CD is assigned a specific number designation and that serves to identify cell

A typical cellular response of a mammary epithelial cell to EGF signal is proliferation. the Kd for the interaction between EGF and its receptor is 1x10^-10 M. Lets imagine that at least 25% of the receptors on a normal cell must be engaged by EGD in order to trigger the cellular proliferation response. What minimum concentration of EGF is required to reduce cell proliferation? (Show calculation). b. Mammary epithelial cancer cells have amplified levels of EGF receptors on their surface. If such a cell has 1000 EGF receptors, as compared to 200 receptors on a normal cell, what minimum concentration of EGF is required to induce cell proliferation in the cancer cell? [Show calculation]. Note that the same number of receptors (not percentage of receptors) must be activated to promote proliferation in normal cells and cancer cell. c. The ambient (unstimulated) concentration of EGF in mammary epithelial tissue is 1x10^-11 M.

Natalizumab is a humanized monoclonal antibody directed at the a4-integrin protein, a subunit of VLA-4, the binding partner of VCAM-1 expressed on endothelium in the central nervous system, and of a4b-integrin, the binding partner of MadCAM-1 expressed on endothelium in the gut. While natalizumab has had great success in alleviating the symptoms of autoimmune diseases such as multiple sclerosis and Crohn’s disease, a small number of patients have acquired life threatening infections of the neurotrophic virus, JC. Why are patients on natalizumab particularly susceptible to a virus infection of the central nervous system?arrow_forward
- Can I get help on creating a concept map for the Introduction provided below? The development of a multicellular organ (such as the brain) from stem cells involves complicated processing.1,2 Proliferating stem cells undergo the fate decision process before developing into tissues or organs. This process is controlled and regulated by a signaling pathway network (called gene regulatory network).3 The network comprises pathways created by the intrinsic and extrinsic factors of the cells, which form the signal transduction to control stem cell fate. There are various signal pathways that have been discovered and studied for tissue development and patterning, including Wnt signaling,4 Notch, and receptor tyrosine kinase.5–7 It has been suggested that cross-regulatory interactions between elements of the pathways (e.g., Wnt and Notch) affect the process of cell fate assignment.8,9 Most components of Wnt signaling have multiple interactions with other signaling pathways (e.g., Hippo/YAP and…arrow_forwardPlease give the answers onlyarrow_forwardExplain, the mechanism of chaperone mediated autophagy.arrow_forward
