27. Provide an example and describe in one sentence how each of the following barriers play a role in the immune response against pathogens: a) Physical barriers: b) Anti-microbial barriers: c) Innate response: d) Adaptive response:
a) physical barriers such as skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other body hair , they protect us from pathogen said to be line of defence mechanism.
b) anti microbial barries: these are also called as complements, interferons or protiens
complements:A number of proteins contribute directly to the body’s nonspecific defense system by helping to destroy invading microorganisms. One group of such proteins is called complement because it works with other defense mechanisms of the body, complementing their efforts to eradicate invaders
interferons or protiens
Interferons
Another group of proteins that provide protection are the interferons, which inhibit the replication of many—but not all—viruses. Cells that have been infected with a virus produce interferon, which sends a signal to other cells of the body to resist viral growth.
c) innate responses:
it is said to non specific response shown by cell, is take part
withhelp of cells said to mast cells, wbc, and some barries said to
skin, mucus,lysozyme etc
d) adapative responces:
The adaptive immune system, also known as the acquired immune system or, more rarely, as the specific immune system, is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth
examples : antibodys, tcells, cd4 and cd8 markers are invloved in the process of elimination of antigen

Describe how Southern blot analysis can be used to determine B cell developmental stages in B cell lymphoma cell lines. Describe one example of how an innate immune mechanism and an adaptive mechanism work together to remove pathogens from the body.
Questions 1. Charlie created a chart in order to keep track of the arms of the immune system so that he could figure out how his body would keep him healthy. Complete the chart with respect to the key hallmarks of the innate and adaptive responses. It is okay to look this information up in a text or on the internet. Hallmark Innate Adaptive Level of specificity Involvement of memory Time for first response to an antigen Time for secondary/repeated...

Compare and contrast innate and adaptive immunity by explaining how they differ is the following 2 questions (I-III). Please answer in complete sentences. How do these 2 types of immunity differ is the timing of their response? How do the receptors as innate and adaptive immune cells differ in what they recognize? Please describe what the receptors on immune cells recognize and what the receptors on adaptive immune cells recognize. Complement proteins normally circulate in the blood and provide early...

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.
