- What is the advantage (in terms of having an effective immune system) of having gene segments that need to be recombined, instead of pre-formed genes for the Heavy and Light chains of immunoglobulins, and the α and β chains of the TCR? What is the cost of having such a system? Please answer asap and type your answer and do not copy from anywhere pleaseThe genetic content of each somatic cell in an organism is the same, but not all genes are expressed in every cell. Why can't cells express all the genes they have?Do not copy in Google or Bartleby. QIESTION • Describe how do they engineer T cells to be used to succesfully treat cancer? • What are another ways in treating cancers?
- Which of the following does not contribute to generating the diversity of antigen-binding specificities among immunoglobulins? a. somatic hypermutation b. random combination of heavy and light chains c. somatic recombination d. activation-induced cytidine deaminase (AID) e. alternative splicing of heavy-chain RNA transcripts.Which of the following is false when considering the CCR5Δ32 mutation? a) The mutation prevents the entry of HIV-1 into a T cell. b) The deletion that produced CCR5Δ32 caused a frameshift which extends the length of the protein product. c) CCR5Δ32 prevents infection by HIV-1 in homozygotes but only delays the onset of HIV symptoms in heterozygotes. d) The protein product produced by CCR5Δ32 is altered in such a manner that it cannot embed in the cell membrane.Antibody diversity is a consequence of differential regulation of antibody gene expression under different circumstances. the huge number of antibody genes. shuffling of antibody genes into different combinations during B cell development. the many types of viruses that exist in nature.
- The T-cell receptor gene segments are arranged in a similar pattern to immunoglobulin gene segments and are rearranged by the same enzymes. While B cells and T cells differ markedly in their functions during an immune response, the two lymphocyte subsets share the enzymatic machinery and overall scheme for generating antigen receptor diversity. This is because: B cells and T cells recognize the same form of antigen expressed by an infecting pathogen. Animals with B cells developed first, and later evolving species then developed T cells. B cells and T cells both need enormous antigen receptor diversity to provide protection against the diversity of pathogens. Antibody and T-cell receptor gene segments are both flanked by similar recombination signal sequences. B cells and T cells both secrete their antigen receptor proteins after they are activated by antigen-binding.T cells and B cells have many similarities in how they produce their highly diverse repertoire of antigen receptors, but one important difference between them is that B cell receptors can undergo somatic hypermutation to alter their affinity for antigen. This is known as ‘affinity maturation’, and the result is that the pool of B cells specific for a particular microbe will increase their binding affinity. T cells do not engage in either somatic hypermutation or affinity maturation. Why not? What potential harm could come from allowing T cells to alter the affinity of their TCRs after they have already left the thymus and have become activated in a lymph node or spleen?The PAMP recognized by TLR3 is doublestranded RNA (dsRNA). Against which pathogens would TLR3 be an effective immune receptor?
- The five classes of immunoglobulin differ in …. Select one: a. None of the above b. Ability to bind various classes of antigens (viral, bacterial etc) c. Make up of the heavy and light chains d. Rate of mutation in the variable domain (i.e. speed at which each class can respond to a new antigen) e. Size of the variable domainIn addition to phagocytosis, neutrophils use a process called NETs. Which one of the following describes this process? A. NETs is a neutrophil process that activates the complement system of proteins, which destroys pathogens. B. NETs are chemicals secreted by neutrophils that trigger the rapid maturation of lymphoid stem cells into lymphocytes. C. A net-like structure of DNA, histones, lactoferrins, gelatinase, cathepsin G, and myeloperoxidase is secreted at pathogens. Together these chemicals destroy pathogens. D. NETs works when neutrophils secrete major basic proteins onto pathogens, destroying the pathogens' cell membranes.When the antigen-presenting cells binds to the T-cell, it will cause the T-cell to increase the amount of a protein called perforin, which is secreted to kill nearby cells. Which of these could INCREASE the amount of a functional perforin proteins produced? a. Increased methylation of DNA near the site of the gene b. Increased binding of a repressor, that decreases the binding affinity between TFIID and DNA c. Increased production of a small RNA that is complementary to perforin mRNA d. Increased O-linked glycoslyation of perforin proteins in the Golgi
