Sandra Peart. Biology Assignment 2 Task1 AC1.1 Major Components & Function of Blood. The four major Blood Components are •Plasma •red cells •white cells •platelet •Plasma is the liquid part of the blood that is made up of 55% fluid, this is the blood’s liquid medium, by itself is straw-yellow in colour. The total volume of blood plasma is about 2.7-3.0 litres in human. The plasma carries carbon dioxide , hormones and waste. •Red blood cells •The red blood cells are called…

result in minor reduction in number of red blood cells (cytopenia). NMA are immune-ablative regimen and are immunosuppressive which is why they cause total engraftment of donor lympho-hematopoietic stem cell. However, a large number of donor T lymphocytes and donor CD34+ cells will be required to aid donor engraftment (Andrea Bacigalupo, 2009). In addition to its lower transplant related mortality…

B-lymphocytes begin this process through activation caused by the BCR’s, B-cell receptors, which are proteins located on the surface of B-cells; this is also caused by the antigen itself or T-cells, this then triggers the B-cell to produce germinal cores which…

and had undergone hysterectomies. The study was approved and guidelines were followed according to the guidelines of the Dutch Federation of Medical Research Associations. Quadruple fluorescent and enzymatic immunostaining of tumor infiltrating lymphocytes and their ligands had been performed using 4 µm sectioned fixed tissues. A citrate antigen was silver stained with anti-cytokeratin AE1/AE3 antibody (IgG1), followed by a mixture of antibodies ab828 (polyclonal, anti-CD8), HNK-1 (IgM,…

Burkitt lymphoma (BL) is an uncommon form of non-Hodgkin lymphoma (NHL), it is a cancer which affects a type of white blood cells called lymphocytes in the lymphatic system. There are three main types of BL (endemic, sporadic and immunodeficiency related). The endemic type of Burkitt’s lymphoma is considerably more common in sub-Saharan Africa, in where it has a close link to Epstein - Barr virus (EBV) and Malaria, whereas the sporadic type only has a 20% association with the EB virus and is…

Cancer is a big issue in America, it is the second leading cause of death. It affects many different ranges of people whether it is there age, race, and ethnicity. “Pediatric acute lymphocytic leukemia incidence rates out of 1,000,000 for ages 0-19 in 2006-2010 for sex and race/ethnicity; 38.4 for boys, 30.2 for girls, 34.2 for non-hispanic white, 18.3 for non-hispanic black, 44.9 for hispanic, and 28.7 for asian american/pacific islander” (American Cancer Society, 2014). Pediatric oncology is…

Majority of T lymphocyte subsets comprises of CD4 (helper cells) and CD8 (cytotoxic cells) cells. CD4 and CD8 cells play their role in cell mediated immunity in normal patients which is very vital to prevent against various diseases. Raised absolute counts of CD4 and CD8…

These immune cells are present in the bone marrow and other lymphoid tissues. Antibodies are a key component of humoral immunity and provide protection through extracellular fluids. They are produced by plasma cells which originate from B lymphocytes. Antibodies are effective at dealing with extracellular (or freely circulating) pathogens. They have various functions such as 1) targeting extracellular pathogens for lysis via phagocytosis or complement, 2) neutralizing receptors on bacterial…

heterogeneous lymphocytes population of innate immune system. They have a natural cytolytic activity, are capable of producing cytokines and chemokines and are involved in the antiviral and antitumor body control. In the quiescent state, an average diameter of NK-cell is about 8.7 microns, while in the moment of its activation it may increase its size up to 10-12 microns (Ferlazzo et al., 2004). This feature was the reason for the initial determination of NK-cells as large granular lymphocytes.…

mutations and MSH1 promoter methylation. The pathologist plays a fundamental role in identifying cancers harboring high microsatellite instability. In fact, there are histological clues suggesting Lynch syndrome: prominent peritumoral lymphocytes, increased lymphocytes (>42 per 10 high-power fields) located within the boundary of tumor cell nests or glands, and tumor heterogeneity, defined as juxtaposed…
