Summary Introduction
Introduction: The innate immunity of insects consists of many protective mechanisms. Their exoskeleton acts as a physical barrier against the pathogens. Their intestinal tract is lined by a chitin layer that checks the admittance of pathogens ingested along with food. The salivary secretion has lysozyme enzyme that breaks down the “cell wall of bacteria”. The immune cells of insects are called as hemocytes. These hemocytes destroy the pathogens by phagocytosis. Some hemocytes discharge “antimicrobial peptides” into the blood circulation and kill the pathogen by destroying their outer membrane.

Which statement is true regarding the nervous system?
a) Damaged myelin on an axon has no effect with its ability to transmit an action potential
b) Depolarization is the reduction of the membrane potential; going from negative to a more positive charge
c) Neuroglia cells are only responsible for providing immunity to the nervous cells
d) Neurons can communicate with other cells without the use of neurotransmitters
1) The immune system and the brain are (two correct answers) :
unrelated to one another
strictly connected
communicate through biological pathways including inflammation
2) How would you define the relationship between the immune system and the brain?
a) Unidirectional (the immune system does not influence the brain)
b) Unidirectional (the brain influences the immune system but only in case of severe physical diseases like cancer)
c) bidirectional (they influence each other)

- Some drugs and toxic compounds interfere with removal of neurotransmitters from the synaptic cleft once they have been released. (1) Explain the two basic mechanisms affected by Sarin nerve gas and the drug Prozac. (2) If you were investigating an autoimmune disease that appeared to interfere with removal of neurotransmitters from the synaptic cleft, and you were able to isolate the causative antibody from the patient's serum, how could you use that antibody to investigate whether it affected one of the two inactivation mechanisms?arrow_forward) Regarding immune memory, which of the following is CORRECT: a. immune memory only occurs after vaccination b. immune memory only protects against viral infection c. immune memory provides and faster and more potent response d. immune memory is due to memory macrophages being formed after first exposure to an antigen e. without B cells, immune memory doesn’t happen 50) Concerning opsonisation, which of the following statements is CORRECT: a. antibodies cleave opsonins to kill bacteria b. complement proteins and antibodies can opsonise invaders c. T cells engulf opsonised microbes more efficiently d. Pasteur demonstrated opsonisation by heat treating anthrax bacilli e. Interferons opsonise virusesarrow_forwardWhat is the correct sequence of events that take place after a professional APC (macrophage or dendritic cell) encounters a pathogen?a. APC engulfs the Pathogen -> enzymes inside the APC breaks up the pathogen -> APC presents the antigen on the outside of its membrane -> helper T ceIl binds to the antigen with its receptor.b. APC engulfs the pathogen -> APC becomes infected -> APC goes through cell death.c. APC does not engulf the pathogen because it is only part of the specific immune response.d. APC engulfs the pathogen -> APC presents the antigen on the outside of its membrane -> NK ceIl kilIs the APC.arrow_forward
- C. ell" to 25. Vaccination is very indispensable to humans and animals to get rid from pathogens. How does a person get antibodies upon vaccination? A. Vaccines have induced B-cells that react if infection invades your body. B. Vaccines today have active version of the pathogen which stimulates B-cells to produce antíbodies against that pathogen.arrow_forward~Multiple Sclerosis (MS) Multiple sclerosis is a neurodegenerative disease in which the body's immune system attacks and breaks down the white matter in the nervous system. 1. What is another word (other than "white matter") for the structure or type of cells that are affected in patients with MS? 2. Given what these cells/ structures do, what effect on neural transmission do you think MS has? ~ Some common symptoms of MS are vision problems, dizziness and vertigo, and difficulty walking. 1. How are these symptoms a result of the effect on neural transmission you described above? 2.

Question 1B: Which cytokine primarily drives the innate anti-viral host response?
