The innate immune system is referred to as the first line in host defense against invading pathogens and preserve host integrity [1]. Of them the innate immune cells have sensors such as macrophages and dendritic cells (DCs) detect molecular components of foreign microorgan¬isms known as pathogen-associated molecule patterns (PAMPs) through PRRs. Its highly developed ability to recognize microbial patterns and host derived danger signals relies on so-called PRRs‚ especially on the TLRs‚ RLRs and

Abstract: Attacks by viruses and bacteria are often serious and sometimes fatal. Yet‚ in many cases‚ the host survives and regains its health. This is because of the presence of antibody and lymphocyte in the blood of an individual that neutralize and attack foreign objects that can cause certain diseases like cancer. In order for us to produce large amounts of antibodies and lymphocytes to suppress foreign objects; we must have an enhanced immune system. The researcher investigated on how to

Harvard University Researchers Develop Cloaked DNA Devices for Medicine and Treatments By John Nassivera | Apr 29‚ 2014 05:20 PM EDT Researchers from Harvard University’s Wyss Institute for Biology Inspired Engineering have created a cloaked DNA nanodevice that can avoid defenses in the body’s immune system. The technology’s design was given inspiration from world viruses‚ according to Gizmag. The nanoscale device could be used for diagnosing

Introduction This report is written upon the instructions given by supervisor Mr. Tim Burch to select a brand of propolis capsules for special promotion in the winter for the company. The objective of this report is to find out the popularity of propolis on market‚ analyse the basic functions of propolis and evaluate the defense system and reputation of Comvita Propolis Capsules‚ the best seller on market. Methodology Two websites about the popularity of propolis were researched. In addition

Outline and Evaluate research into the relationship between the immunes system and stress-related illness. Stress has been widely identified to be linked with illness‚ which has therefore attracted researchers to investigate the relationship between the immune system and stress. Cohen et al for instance conducted a study where 369 participants were asked to complete a questionnaire which measured their Psychological Stress Index‚ consisting of a scale measuring their own perception of their stress

The role MHC class II plays on the immune system is that some of its genes code for proteins that will be expressed on the surface of the immune system cells. Peptides which are protein fragments outside the cells will allow these proteins to be attached to them‚ if these proteins are recognised by the immune system as foreign (such as viral and bacterial) the MHC will send a signal to the immune system to trigger an immune response against the invading bacteria or virus. The HLA class I and class

The safe structure is an arrangement of cells‚ tissues*‚ and organs that chip in to shield the body against ambushes by "remote" interlopers. These are basically life forms (germs) minute‚ sullying realizing natural substances‚ for instance‚ microorganisms‚ contaminations‚ parasites‚ and developments. Since the human body gives an immaculate space to various microorganisms‚ they endeavor to break in. It is the safe structure’s business to keep them out or‚ missing the mark that‚ to hunt out and obliterate

Immunology is defined as a science that deals with the immune system and the cell-mediated and humoral aspects of immunity and immune responses. An immunologist deals with humans that have an immune response that is not considered normal. For example they treat patients’ that have AID’s‚ Immunodeficiency’s‚ and some autoimmune disorders. Immunology began when Edward Jenner developed a vaccine for small pox‚ and lead to a system of programs to immunize people‚ though this is not all immunologists

Humor Do you know that humor can cause positive effects on our immune system? According to certain research‚ it actually activates our immune system‚ reduces our stress hormones and leads to muscle relaxation. Because of these effects‚ our immune system will be strengthen. As a result‚ humor lets our body feel so relaxed. Humor is a daily medicine that we should take because it keeps us young‚ happy and optimistic. According to Merriam Webster’s Collegiate Dictionary‚ humor means

1. Explain what clonal selection theory is and its role in humoral or antibody-mediated immunity. Clonal selection theory is a rationalization for the growth of lymphocyte specificity and diversity during immune development. This theory demonstrates how immunological memory can deliver a fast reaction when coming into contact with an antigen that has been seen for the second time. Specifically‚ the clonal selection theory is based on the concept that premature‚ undifferentiated lymphocytes in the
