The Secret Powers of Food - Assignment Example If we delve into the root of the issue, we will find out that food plays a huge role in people’s lives and its impacts on their outlooks and beliefs are impressing. To justify this, I have conveyed an interview. My interviewee is Mr. Wilson, the father of my neighbor, he is 47 years old. The man was glad to share his life experience and food story with me. I have come up with some interesting ideas, based on the information given by my interviewee and the book Toast: The Story of a Boy’s Hunger by Nigel Slater. As a result, I strongly believe that food helps people to socialize, to show one’s affection, it evokes memories, shapes one’s lifestyle and attitude to culture. To begin with, food has become an integral part of social life. It may sound like nonsense, but food plays an enormous role in socialization between people. If we think about any occasion which implies gathering of people, we probably will not come up with any example that would not include food. Every celebration, holiday, date and even some official meetings always include some sort of ingestion – lunch, dinner or a pair of cocktails. Possible reasons for it may be that by means of food people interact nonverbally. It brings interlocutors together and helps them to relax and communicate freely. With the help of food a positive atmosphere is created which provides a beneficial outcome of any meeting. Furthermore, we may claim that food is a way of showing one’s love and care. It is through food that every mother shows her children how much she cares about them. I’ve interviewed my neighbor’s father, Mr. Wilson, and he told me what food meant to him and to his family. When he was a child, Mr. Wilson used to live in a city, but his weekends and summer holidays he spent at his granny’s, in the suburbs. There was a little farm there with plenty of fruit and vegetables and some domestic animals, such as chickens, geese and a few pigs. His  grandmother always tried to show her affection to her beloved grandchild by means of food.

For the in vitro study immortalized human keratinocyte cell line HaCaT, primary bovine PalF cells and NIH 3T3 cell lines which expressed the HPV-16 E5 protein was used and some NIH 3T3 expressed HPV-6 E5. After subsequent culture, suitable immunological assays were carried out to detect the presence and localization of the MHC class I molecules in these cells. While in the control cell lines MHC molecules were localized both in the cell surface and within the GA, in the HPV-16 E5 expressing cells the molecules were found exclusively in the GA. The study also showed that HPV-16 E5 did not affect the synthesis of MHC molecules unlike BPV E5 and that the expression of the E5 protein did no affect the transporter protein responsible for the transport of MHC molecules. To determine the effect of interferon , all the cell lines were treated with interferon ÃŽ ², which resulted in all the cell lines having similar levels of MHC molecules and also the molecules were found on the cell surface in the E5 expressing cell lines thus proving that the inhibition on transport of MHC molecules is reversed upon treatment with interferon. The study also noted that E5 did not down regulate the expression of HLA-C and E, involved in inhibiting NK cell-mediated lysis. The two most striking limitations observed is: the study was carried out in vitro and in vivo reproducibility needs to be ascertained and secondly, the detection of the E5 protein was carried out by RT-PCR rather simpler techniques. The two major strengths include: this is the first paper to show the immune evasion mechanism by the HPV E5 protein and the cell lines used are a good model for understanding the mechanism and finally, the study explores the gene level expressions involved in the down regulation process of the MHC molecules. In
