Complement system

Biological functions: The main biological functions for CRP to determine via its ability to identify pathogens and injured cells of the host and mediate their elimination via activating the complement system and phagocytic cells (Brundish and Baddiley,1968 ; Weiser et al., 1997). CRP binds to microorganisms and mediates their killing to more recent observations of protection against bacterial pathogens in CRP transgenic mice. The most significant evidence has supported the notion that CRP plays an important role in host defense. CRP mediates protection due it supports three main effector functions, firstly activation of complement, secondly the induction of phagocytosis and finally plays a key role in opsonization (Szalai, 2002a). More relevant to the function of CRP is human secretory phospholipase A2 with CRP may serve to promote phagocytosis of injured cells and tissue debris, an enzyme secreted by liver as an acute phase protein…

The structures, antigen binding, and abilities to activate complement are important aspects to understand different drugs relating to autoimmune diseases. Each of the four drugs, infliximab, Adalimumab, Etanercept, and Certilizumab, have different antibody structures, leading to differences in function and binding abilities. The drug infliximab is a chimeric monoclonal antibody, containing 25% mouse-derived and 75% human-derived amino acids. The drug Adalimumab is a fully human monoclonal…

foundational studies and theories were established. These “schools of thought” were differentiated by support for either rational or natural systems as well as administrative practices. Central themes across the literature examined the primary differences between rational and natural systems and the selected schools of thought. Theories such as “Taylor’s Scientific Management”, “Fayol’s Administrative Theory”, “Weber’s Theory of Bureaucracy”, and “Simon’s Theory of Administration Behavior”…

They explain how the activity system define a group of people who share a common goal or motive. I completely agree on how an activity system allow certain communities are structurally connected. This is a great way to help you understand community relationships. Activity system is a good system because it “sees all aspects of activity as shaped over time by people’s social interactions with each other and the tools they use” (1). Everyone is in an activity system even if you don’t realize it.…

How Shake Shingle Metal Roofing Compares To Wood Shakes If you love the look of a wood shake roof but hate the thought of all the maintenance a wood roof needs, then you should consider getting a shake shingle metal roof instead. You'll have the look you like, but none of the upkeep required for real wood. Here's how the two types of roofing compare. Appearance You may imagine metal roofing to be in long sheets like you see on barns, but it actually comes in different forms. The metal can be…

Fundamentals of a Roof Warranty Learn the basics of roof warranties and what homeowners should know before they buy. Roofing contractors and roofing material manufacturers both offer a variety of warranties designed to protect their customers from incurring excessive costs in the event of roof damage. However, it is essential for homeowners to understand a few basics about warranties, including what they are and are not, why reading the fine print is important, and how a warranty can benefit…

human immune response is a complex, layered system that uses multiple defense mechanisms which function in harmony to protect the body from infection and illness. There are two main types of immune response, the innate and acquired, and while these responses are related and sometimes overlap, they use separate processes to defend against invaders. Working as a whole, innate and acquired immune responses protect the body from infectious organisms. Infectious organisms that can cause disease…

neutrophils, Fc factors, and complement activation (Ludwig, 2012). EBA pathogenesis and autoantibody- induced cellular damage can be understood as: (i) binding of autoantibody to antigen, (ii) Fc- factors of blister production, and (iii) the diapedesis of neutrophils (Ludwig, 2012). Anti-COL7 Antibody Binding to Antigen Anti-COL7 autoantibodies were identified after they obtained a fluorescent labeled and injected into mice (Iwata & Kitajima, 2010). Within minutes of the injection, anti-COL7…

The interaction between the CNS and the systemic immune system is delicate, being limited by the presence of the blood brain barrier (BBB), which renders the CNS immune homeostasis in a dormant self-tolerant state (1). Selective permeability of the BBB plays a crucial role in regulating the entry of specific molecules into the CNS and excluding most macromolecules from passing into the brain (2, 3). This unique feature of the BBB also prevents leakage of neurotransmitters into the circulation.…
