The Human Immune System And Its Effects On Disease...

The human immune system has advanced to distinguish between and eliminate disease-causing microorganisms. Nevertheless, a symbiotic relationship has been developed with several species of bacteria that not only inhabit the gut, but also make up the natural commensal flora or microbiota. The microbiota, being essential in the breakdown of nutrients, helps prevent colonization by potentially pathogenic bacteria. Also, the gut commensal bacteria appear to be vital in the growth of an efficiently functioning immune system. Many studies have been done to demonstrate that various species of microbiota can cause responses from different types of immune cells such as Th17 cells and Foxp3+ regulatory T cells, suggesting that the properties of the microbiota can have a significant influence on immune response. Although the microbiota is found in the gut, it seems to have a substantial effect on immune response. In fact, specific gut commensal bacteria have displayed a correlation in affecting disease development in other organs besides the gut, and depending on the type of species, can have a wide range of effects on disease, whether that being inhibition or protection. It has also been determined that the initial composition of the microbiota is significant through the effects of milk attained by either breastfeeding or formula feeding. All in all, the gut microbiota has been found to be significant in the development of the host’s immunity to various pathogenic microorganisms, andShow MoreRelatedTo humans, having a healthy immune system is essential. Our immune system is important because it900 Words   |  4 PagesTo humans, having a healthy immune system is essential. Our immune system is important because it helps the body fight any foreign bacteria, viruses, and diseases by attacking it, which is why we must take care of it as much as possible by strengthening it. But this so called defense system can also cause problems such as attacking donated organs or blood from another individual, unless the organs or blood are carefully matched. It may also overreact to harmless invaders such as pollen grains, whichRead MoreHuman Therapeutic Ways Of Addressing Cancer Treatment866 Words   |  4 PagesAs the world continues to suffer from these devastating diseases, researchers continue to find alternative therapeutic ways of addressing cancer treatment. It is on this premise that various immunotherapeutic alternatives have emerged and currently garnering the greatest level of attention and already raising hope throughout the world in addressing the treatment of NSCLC. However, this can no longer be viewed as a discovery but a wave in the medicine world that began in the 20th century. VariousRead MoreSymptoms And Treatment Of Yellow Fever1670 Words   |  7 Pagesassociated with extensive hepatic necrosis and jaundice. The disease is said to be caused by insect-borne flavivirus that is also a single stranded RNA virus. (Strayer, R. R. D. (2011 ).Yellow fever virus is an Alpha virus belonging to the Flaviridae virus family that uses primates as monkeys as its primary reservoir and transmitted to hosts such as humans using mosquito vectors called Aedes aegypti. Once the virus has been introduced into humans, several clinical manifestations present in the beginningRead MoreThe Immune System : A Complex Network Of Innate And Innate Immune Systems1254 Words   |  6 PagesThe immune system is a complex network of innate and adaptive compartments that work together in order to protect and fight against pathogenic invaders. The immune system also acts as a regulator of host homeostasis in order to ensure that the body is operating under optimal conditions. The composition of microbiota is associated with the adaptive and innate immune systems, which work together in order to maintain a constant relationship between the increasingly different microbiota and pathogensRead MoreHuman Breast Milk : A Review On Its Composition And Bi oactivity1481 Words   |  6 PagesThe article â€Å"Human breast milk: A review on its composition and bioactivity† was found on the database called CINAHL complete. The terms â€Å"breast milk† and â€Å"health† were used during the search. The abstract of the article is the following: â€Å"Breast milk is the perfect nutrition for infants, a result of millions of years of evolution, finely attuning it to the requirements of the infant. Breast milk contains many complex proteins, lipids and carbohydrates, the concentrations of which alter dramaticallyRead MoreThe Roles Of Carbohydrates And Their Cooperation Within The Immune System1508 Words   |  7 PagesThe trouble for fully understanding their roles thoroughly stems from the â€Å"nontemplate nature of their synthesis.† This paper calls attention to what is known about the different binding partners of carbohydrates and their cooperation within the immune system, namely microbial (non-self), tumor (altered-self), and host (self). DNA and RNA can be thought of as polysaccharides with phosphate-linked polyribose cores. Without carbohydrates present, it would be impossible for them to form the scaffoldingRead MoreA Human Papillomavirus Vaccine1591 Words   |  7 Pagesasil: A human papillomavirus vaccine [GENERAL INTRODUCTION] The modern world is considerably lucky in the fact that vaccinations have been created and made readily available thanks to Edward Jenner and his development of the first vaccine for smallpox in 1796. Since the 18th century, there have been about fifty different vaccines created to protect humans against bacterial and viral diseases. A vaccine is a substance that can be administered through needle injections, by mouth, or by aerosol toRead MoreChronic and Infectious Disease Paper790 Words   |  4 PagesChronic and Infectious Diseases Paper Chronic disease is a fight that many fight each day. Some argue that chronic disease can be prevented with good healthy obtained through a good diet and exercise. Individuals should seek out a doctor when he or she wants to obtain good health. Each person definition of good health would be different because his and her levels of protein, carbohydrates, fiber and fats will be different. This paper identify characteristics of chronic disease, Examine the relationshipRead MoreModern-Day Vaccine Development Raising Eyebrows Essay1580 Words   |  7 PagesIntroduction Vaccine development is an old and complicated process, often requires more than a decade to complete. The modern system of vaccine development, regulation and testing was developed during the 20th century. To engender a vaccine mediated immunization or protection has been a major challenge. Presently available vaccines work primarily through the induction of the antigen specific antibodies. The effectiveness of any vaccine is determined by the quality of the antibodies, as their workRead MoreVaccines And Its Effects On Children1503 Words   |  7 PagesLife as we know it was just a dream for most families in the 19th and 20th centuries- they were consumed with fear of having family members die from awful diseases, while that is the last thing on most of the world’s minds now. Vaccines have transformed human life. Parents should vaccinate their children because it saves lives, the vaccines are safe, and the risks of not vaccinating can harm children more than the vaccines the mselves. Vaccines were created in 1796 by Edward Jenner, an English scientist
