Nicole Perry 7.06 Immune System Lab Report Thoroughly washing your hands can be one of the best ways to prevent the spread of pathogens that cause illnesses. Our bodies have several lines of defense to fight infections. It is very important to do what we can do to avoid the pathogens from entering our system in the first place. Our hands pick up microscopic pathogens from objects that were touched by people who may not have washed their hands very well. When we forget to wash our hands or don’t

Immunology January 27‚ 2010 Lecture 2 Innate Immunity‚ the signal transduction and cytokine production When you’re exposed to a microbe‚ your body has innate immune responses that can kill the microbe right away‚ there is no recovery or memory period. It is the very first response. If you amount an affective innate immune response‚ you don’t need to develop an adaptive immune response. In reality‚ most cases‚ you get infected and the innate immune responses deal with some of the microbe and

Time spent during prenatal development creates a special bond between the mother and child. During this time‚ biological factors such as hormones pass through the placental barrier from the mother and into the fetus’ bloodstream. Additionally‚ umbilical cord transports materials such as nutrients to the fetus. Due to the direct connection‚ mothers are strongly advised not to consume teratogens such as alcohol‚ drugs‚ or other substance that may be detrimental to a fetus during pregnancy. Intangible

STRATEGIES THAT ARE USED BY BACTERIAL PATHOGENS TO EVADE HOST ANTIBACTERIAL PEPTIDES AND PHAGOCYTES” The mammalian immune system has two major components; the innate and the adaptive immune system. The innate system is usually the first line of defence and it acts as a strong roadblock to invading bacterial pathogens through direct mechanisms such as inflammation‚ phagocytosis‚ complement system activation‚ antibacterial peptides and indirectly by activating adaptive response through antigen presentation

A Prion is a normal protein that is found on the membranes of cells. The normal Prion protein (PrPC) consist mainly alpha helix rich 30-35kDa glycoprotein with 209 amino acid sequence and one disulfide bond (1). The disease causing form of normal prion protein named after scrapie (PrPSc) occurs when properly folded normal prion protein change its conformation. Although the exact tertiary structure of PrPSc still remains elusive but the previous studies have shown that the secondary structure of
