Innate immune system

Introduction The immune system is a collection of cells, tissues and molecules that protect our body from toxins and microbes in the environment. It serves as our defense against molecules that our body does not recognize as its own. This system contains two divisions: the innate immune system and adaptive immune system. Both systems differ in the types of cells produced and the time and length in mounting a response. Inflammatory bowel disease is a chronic inflammatory disease including…

The threshold hypothesis states that T cells may only be activated when a certain amount of antigens are located on the antigen presenting cells (APCs). Additionally, a certain level of damage to the host will cause innate immunity to respond and begin to fight back against an invading pathogen. Looking at both of these parts of the theory, it would be best to find the amount of vaccine that allows for adequate presentation on APCs and T cell activation while not going…

On basic note Presence Innate immunity is something already present in the body. Adaptive immunity is created in response to exposure to a foreign substance. Specificity Non-Specific Specific Response Fights any foreign invader and rapid Fight only specific infection and slow(1-2 wks) Potency Limited and Lower potency High potency Time span Once activated against a specific type of antigen, the immunity remains throughout the life. The span of developed immunity can be lifelong or short.…

not as effective as it can be, especially for individuals that have compromised immune response. The body’s immune response system has an essential resistance and adaptive immunity as its first line of defense. When the front-line defense (innate) immunity fails to protect the body against microbial pathogens the second line of defense (adaptive) which is more specific is activated (H. ,2012, September 11). The innate immunity contains different cell forms that generates a barrier stopping…

a healthy individual, the bloodstream remains sterile – free of any pathogens. The immune system, which is responsible for defending the body against pathogens, is a very complex and vital body system. The immune system involves both innate and adaptive immunity. Innate immunity functions as the “first responder” system of the body. The skin, the mucous membranes are the first line of defense in innate immunity. The skin and mucous membranes serve to prevent microbes from entering…

When I think of the body’s immune system, I think of the video game Pac-Man. Pac-Man gobbles up all the little dots in his way, our body works hard to gobble up germs in its way, much the same as Pac-Man. There are also enemies that try to attack Pac-Man and attempt to make him lose a life, in the same way, our body has to defend against viruses that try to attack it. In the game, you are successful if you are able to keep Pac-Man alive by gobbling up everything in its path before they attack…

Abstract Psoriasis is a chronic auto – immune disease that is believed to be inherited and most common in women. There are seven types of Psoriasis (Plaque Psoriasis, Guttate Psoriasis, Inverse Psoriasis, Pustular Psoriasis, Erythrodemic Psoriasis, Nail Psoriasis and Psoriatic Arthritis), but the most common is Plaque Psoriasis and it affects 4 million people in the United States. It is characterized by raised, inflamed, patchy, red skin covered with white scales that is cause by an excess of…

influence the developing immune system in responses from cytokine balance, to lymphocyte responses, to antibody induction (3). In utero, mammals are essentially sterile, and colonization by these microbes begins at birth, and expands throughout life as the host is exposed to foreign organisms through their environment (4). Because each person’s exposure may differ with their unique…

1. The immune system is a group of organs including your cells, proteins, and structure of the lymphatic and circulatory system that work together to keep the human body healthy. The immune’s system primary function is to protect all other organs systems from attack such as things like bacteria or prevent you from getting sick. Our body’s immune system includes three major parts. The first main defense of the immune system is known as barriers which is the first line of defense. Barriers…

presented with subcutaneous nodules, arthritis, lymphadenopathy, fever, weight loss, anemia, and central nervous system involvement.1 Systemic lupus erythematosus (SLE) is an autoimmune disorder that causes chronic inflammation of connective tissues, with multifactorial pathophysiology and heterogeneous clinical manifestations. The autoimmunity is conferred by dysregulation of aspects from both innate and adaptive immunity, which leads to the production of autoantibodies. In SLE the most…
