immunity. Protection can be acquired either by passive or by active immunization.Passive immunization involves transfer of antibodies obtained from an immune donor to a nonimmune individual and results in temporary immunity. Currently‚ antibody-based therapies represent a form of treatment for disorders induced by venoms or toxins and for viral infections. Injections of antibody preparations derived from immunized human donors are used for the prophylaxis and treatment of tetanus‚ rabies‚ and pneumonia

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

Defence against Disease and the Immune System In this essay I have distinguished clearly between active/ passive‚ natural/artificial immunity and described some methods of vaccine production. I have critically compared the effectiveness of the smallpox vaccination programme with programmes aimed at control of measles‚ polio‚ influenza‚ malaria and cholera. Introduction (Immune System‚ 2012) “The immune system is made up of a network of cells‚ tissues‚ and organs that work together

Located in the upper left side of the abdomen‚ next to the stomach‚ the spleen is neatly tucked in between the pancreas‚ stomach‚ and left kidney (Laparoscopic‚ 2013).The spleen is typically around 4 inches long

All reagents were leaved to reach room temperature before use‚ and then shacked thoroughly with no foam. 2. The number of strips required for the test was fixed on a plate holder. 3. Sample inactivation (dissotiation of HCV core antigen-antibody complex step). 4. 100 µL of inactivated sample and HCVcAg standard were added to Anti-HCVcAg Antibody Coated Plate. 5. The Plate was Covered and incubated

Immune-mediated thrombocytopenia is likely identified with forms of neoplasia because the antibodies against tumor antigens may initiate the destruction of platelets. Common forms of neoplasia seen with thrombocytopenia include lymphoma‚ mast cell tumors‚ adenocarcinoma‚ and hemangiosarcoma. All causes of immune-mediated thrombocytopenia should

rapidly worsening symptoms using donated blood to temporarily modify the immune system; this is expensive and has short-term benefits. The other is plasmapheresis‚ an expensive therapy with ephemeral relief where the patient’s blood is exchanged for antibody-free blood with albumin. Another opportunity some patients tend to choose is complementary medicine. Spiritual escapes such as meditation‚ conversation‚ and exercise help ease side effects and relax the patient (Conquer Myasthenia Gravis 2016) .

slides were prepared using the Antibody Immunohistochemistry procedure for GCR protein (PA1510A Life Technologies at 1:1000) that used DAB to stain the collected tissue to locate GCR proteins. Primary antibody is created so there is a high affinity for the protein in the experiment. For this study‚ the primary antibody is selective for GCR protein. The secondary antibody has a high affinity for the first‚ and is also bound to HRP. In the presence of GRCs‚ the primary antibody will bind to the GRCs. The
