To what extent can knowledge of tumour associated antigens be useful Essay - 1

To what extent can knowledge of tumour associated antigens be useful in the management of cancer patients Illustrate your answe - Essay Example The antigens are expressed in different categories depending on the gene mutation of proteins in the Tumour cells. These categories define the classes of tumour-Associated antigens, which are Unique Tumour Antigens, Cancer Testis Antigens, Differentiation Antigens, and over expressed Antigens in relation to T-cells antigens in cancer (Gires & Seliger 2009). Unique Tumour Antigens are specific antigens in the tumour cells recognized by CD4 + and CD8+ T cells as a result of gene mutation and fusion of proteins (Gires & Seliger 2009). These tumour antigens have specific expressions to the tumour cells from which the proteins are altered thus only a few are shared in different T-cells. Unlike Unique Tumour Antigens, Cancer Testis antigens go through additional mutations that bring about a restricted expression on cancer cells. These antigens encompasses a group of antigens recognized by CD4 + and CD8+ T cells and they are basically antibody target (Gires & Seliger 2009). Differentiation Antigens are characterized by malignant cells associated with cluster differentiation that are not particularly tumour related. They are directed towards specific antibodies in the same lineage rather than normal body cells (Gires & Seliger 2009). ... e, Cytotoxic T-cells detect antigens on Tumour cells, which can lead to cell damage when Cytotoxic T-cells secrets negative cytokines that destroys normal cells (Crowley 2011). Immunotherapy uses the same kind of approach since it kills small metastatic cells hence creating adaptive immunity when the antigens get to the body (Miermont 2008). Antigen- specific T- cells are introduced in the body through vaccines where Lymphocytes create a hormonal immune response by being activated to eliminate Tumour Associated antigens immediately they recognize invading antigens (Nagorsen & Marincola 2005). Tumour- Associated Antigens are helpful when it comes to human cancer management. The importance of these types of antigens is dependent on the type of cancer and the level in which it has been realized. It has been realized that tumour associated antigens are very attractive diagnostic and therapeutic approaches to human cancer (UICC 2003). When applied especially when the cancer symptoms are n ot conspicuous, it can assist in revealing the areas affected by cancer cells. For example, Hodge, Grosenbach & Schlom (2002), expresses an experiment where they introduce vectors (antigens) in the body of a patient in form of a vaccine. These experiments are done using different antigens as a source of signal. The introduction of the antigens helped create immunity since it identified the specific areas affected. With introduction of antigens in different capacities, the immunity went on growing with each vaccine administered. According to Kumar (2012), cancer can be successfully treated by a combination of chemotherapy, surgery, radiation therapy and immunotherapy. Having knowledge about tumour-associated antigens can assist a patient to know the right combination for his particular

Marketing planning - Assignment Example In addition, there are approximately 20,000 garages and other service outlets, which involve in selling of new tyres as a segment of a broader service offering. The whole industry combined employs near about 16,000 people. The tyre retail sector is also engaged in the sales of replacement tyres. The value of sales amounts to about  £3.2 billion a year. Even though automobile tyre industry is an exuberant sector, which has witnessed an unprecedented growth over the past few years, concentration of internet retailers, often termed as e-retailers, remains quite small (3%). However, in the recent past, concentration of the same seems to be growing at a rapid rate with many players entering the already competitive market. With the scenarios presented above, it is quite clear that the competition that Guildford Tyres Co. Ltd. deals with is immense. They are tyre retail and automotive service specialist, who have been in service since 1967. It is a family owned and administered business, which has become the leading autonomous tyre specialist in the county of Surrey within the United Kingdom (Guildford Tyre Company,  2012a). The products sold by the company ranges from car tyres, 4x4 tyres,  van tyres, cycle tyres, motorcycle tyres, wheels, brakes, batteries to shock absorbers (Guildford Tyre Company,  2012b). The services offered by the company includes tyre fitting, mobile tyre fitting,  wheel alignment and servicing, puncture repairs, tyre wholesale and other associated services (Guildford Tyre Company,  2012c). The political landscape of the UK is established in the ethos democracy and steady framework of governance, which ensures a certain degree of uniformity in its policies. After the world wars, the UK established itself as a major global force, which was stimulated by a swift economic development. One of the major contributors of this development was the tyre industry and it continues to be the same in the contemporary society. UK’s strong trade
