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.

- What 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_forwardA vaccine IMAGINERIX was introduced against a new Gloomy virus (hypothetical names). While the vaccinated population were immunized against Gloomy virus, a few reports followed, claiming that some developed symptoms of multiple sclerosis. (a) What is the possible connection between the use of Imaginerix and multiple sclerosis? (b) State ONE possible treatment option for multiple sclerosis.arrow_forwardC. 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
- It's the first day of university exams and Sarah has woken up with a sore throat, headache, muscle aches and a low grade fever. Her GP diagnoses her with a viral infection and tells her to go home, rest and drink plenty of fluids.Question 1A:Name one of the most likely innate immune system receptors to initially detect this infection and where in host cells this receptor is located? Question 1B: Which cytokine primarily drives the innate anti-viral host response? Question 1C: Describe the antiviral signaling events that take place inside an infected cell in response to this cytokine. Question 1D: Provide a biological explanation for why Sarah was more likely to suffer a viral infection during her periodarrow_forwardHuman immune system a) Pathogen-associated molecular patterns are conserved molecular structures produced by microorganisms, but not by host cells. b) A virus-infected host cell that displays a viral antigen via MHC class I molecules may become a target of cytotoxic T cells. c) Secreted MHC Class I proteins present in blood plasma can function as opsonins. d) Both (a) and (b) are correct and (c) is incorrect e) Statements (a), (b) and (c) are all correctarrow_forwardThese cells synthesize and secrete which of the following molecules: Choose one from the following: (A) perforin and granzymes (B) serotonin (C) immunoglobulin M (D) interleukin-2 (E) interferonarrow_forward
- 7.In some viral infections, interferons, which are hydrophilic, are secreted by some white blood cells. These bind nearby cells causing uninfected cells to produce protective antiviral proteins. Based on the chemistry of this interferon (ligand/signaling molecule), are receptors required for it to exert it’s action, if so where. Select yes/no for receptor; Select location if applicable yes a receptor is required no a receptor is not required receptor location: cytosolic receptors receptor location: nuclear receptors receptor location: plasma membrane receptorsarrow_forwardPlasma cells (A) tag pathogens with antibodies (B) are a fragment of a megakaryocyte (C) attack tagged pathogens directly (D) are a part of the innmate immune systemarrow_forwardplease answer 15,16,17arrow_forward

A small population of plasma cells secrete pathogen-specific antibody long after pathogen clearance from the body. B. Memory T cells and memory B cells originate in secondary lymphoid tissue through colonal expansion. C. Memory T cells are produced during secondary immune responses, but not during primary immune responses. D. During a primary immune response, effector B cells outnumber memory cells. E. protective immunity persists for the same period regardless of the type of pathogen F. Memory B cells generated in secondary immune responses are more effective than memory B cells made in primary immune responses because of affinity maturationarrow_forward
