Homework Answers
1. The main role of the immune system in the evolution of cancer cells is that many immune cells protect the cancer cells from various kinds of immune responses. For example, tumor-associated macrophages (TAM) helps in the angiogenesis of the tumor which provides nutrition to cancer cells and they also protect the cancer cells by decreasing the infiltration of cytotoxic CD8+ T cells. Other than macrophages there are other immunosuppressive cells which helps in the growth of cancer cells. Inflammation is a well known immune response but a chronic inflammation can lead to DNA damage and cancer.
2. Cancer cells mainly originate due to mutation in the DNA of growth factors, tumor-suppressive genes or oncogenes. The mutation either leads to inhibits state or constitutively active stat which are beyond cellular control leads to uncontrolled growth of the cell snd cancer.
3. Cancer cells can affect the adaptive immune system in many ways. They don't activate the NK-cells by maintaining normal number of MHC class I on the surface like somatic cells. They secrete different chemokines and cytokines which helps to attarat different kinds of immune cells and maintain atolerogenic niche for the growth of cancer cells.

Given what you know about the immune response, propose a detailed explanation about how the immune system responds to COVID-19. Be sure to describe each phase (physical barriers, non-specific immunity, specific immunity). You may draw a step by step diagram labeled or your may describe the process in words Be sure to address the role of macrophages, NK cells, B cells, and T cells.

QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on) is passed on to each generation, increasing the number of possible responses over time. Each lymphocyte is coated with many...

The Case Study in Cancer Part I Ann is a 27-year-old nurse working at the local hospital in surgery. She had worked hard to move into the specialty, and she was enjoying her career, friends, and family. She and her partner had been living together for about a year, and she was content. As a nurse, Ann knew the importance of doing breast self-exams, and did them regularly. In the shower one morning, she felt a lump she wasn’t familiar...

Seope: This science commentary claims that epigeneties plays a role in cancer cells becoming therapy-resistant. The language used is generalized for the non-scientist and does not include any molecular details, such as methylation of a specific nucleotide in an allele or modification of a specific histone tail amino acid.

please answer all the question to get a like. Part III Dr. Hernandez sits down with Ann and her partner. The doctor is sorry to report that Ann has breast cancer; however, because it was caught early and responds to estrogen and progesterone, the prognosis is good. At this point it looks like the cancer is stage 1. However, as Ann is young, the doctor wants to perform a couple of tests. The first test is a genetic sequencing test...
