ONPS1050 Guidelines For Postgraduate Report And Forms

ONPS1050 Guidelines For Postgraduate Report the Report Forms Part Of T

The report forms part of the assessment for the course- it is worth 35% of the final mark. Due date for written report: midnight 10th October (week 13). The report is to be submitted through the Turnitin Assessment task dropbox. Make sure you submit to postgrad. Late submission will be penalised at 10% per day.

Extensions only by Special Consideration application. As a general indication, the Turnitin % match should be less than 10%. The way to ensure this is to write everything yourself! Do not copy and paste, even if you rearrange. This is plagiarism.

You can submit to Turnitin as often as you like up to the due date. Just overwrite the old submission. The report: Immunotherapies. The report is to be up to 2,500 words in length, excluding references (no less than 2,000). Put the word count on the Title page.

No listed word count, or exceeding the limit, will lose a mark. The style is relatively flexible, but should contain such divisions as a Title page, table of contents, introductory paragraph, various sections describing your findings, a concluding paragraph and bibliography. Figures are welcome, but if they are not your own, must be referenced. The report must include references from the primary literature (e.g. PubMed).

References must be cited correctly in-text and listed at the end of the report, using any standard referencing style. Example below. 1 Drickamer, K. (1999) C-type lectin-like domains. Curr. Opin. Struct. Biol. 9, 585– Figdor, C.G., van Kooyk, Y. and Adema, G.J. (2002) C-type lectin receptors on dendritic cells and Langerhans cells. Nat. Rev. Immunol. 2, 77– Gantner, B.N., Simmons, R.M., Canavera, S.J., Akira, S. and Underhill, D.M. (2003) Collaborative induction of inflammatory responses by dectin-1 and Toll-like receptor 2. J. Exp. Med. 197, 1107–1117

The report should begin with a section that summarises the general field of immunotherapy. This will comprise the first half of the report. The next part of the report must include two specific examples of where immunotherapies have been applied to assist in the treatment of a medical condition. The condition does not need to be the same for each example. The examples should be reviewed in some detail, with literature cited where appropriate.

Multiple citations should be given- this section is not to be a review of a single article for each approach. Also, the treatment can be either in current use, or experimental (in which case you may detail research using animal models). The report will be marked on how well you demonstrate an understanding of the immunological principles involved. I am happy to discuss the report with you to make sure you understand what I want. However, I cannot read drafts of the report.

You can choose any target condition you wish; examples may be cancer, autoimmune disease, infectious disease, transplantation etc. Remember that, in the lectures to come, you will hear about several techniques that may be applied to your task.

Paper For Above instruction

Immunotherapy represents a revolutionary approach in modern medicine, leveraging the body's immune system to combat diseases such as cancer, autoimmune disorders, infectious diseases, and conditions requiring transplantation. Over the past few decades, advances in immunological research have culminated in the development of various immunotherapeutic strategies that aim to enhance, suppress, or modulate immune responses for therapeutic benefit. This report provides an overview of the fundamental principles of immunotherapy and discusses two specific applications—cancer immunotherapy and autoimmune disease management—emphasizing their mechanisms, current status, and potential future directions.

Overview of Immunotherapy

Immunotherapy is predicated on the understanding that the immune system can distinguish between self and non-self entities and can be harnessed to target pathological conditions. The central immunological concepts underpinning immunotherapies include immune activation, immune suppression, antigen presentation, immune checkpoint regulation, and cellular immunity. For instance, T cell activation involves antigen recognition via the T cell receptor in conjunction with major histocompatibility complex (MHC) molecules, providing the foundation for many therapeutic strategies.

One prominent form of immunotherapy involves monoclonal antibodies tailored to target tumor-associated antigens or immune checkpoints such as PD-1 and CTLA-4. These immune checkpoint inhibitors release the "brakes" on the immune system, enabling T cells to more effectively recognize and kill tumor cells (Topalian et al., 2012). Another major development is the use of cancer vaccines designed to prime the immune system against specific tumor antigens (Melero et al., 2014). Beyond cancer, immunotherapies aim to modulate immune responses in autoimmune diseases, either by expanding regulatory T cells (Tregs) or employing cytokine therapies, thus restoring immune tolerance (Sakaguchi et al., 2010).

Immunotherapy in Cancer Treatment

Cancer immunotherapy has transformed oncology by providing durable responses in cancers previously deemed intractable. Checkpoint inhibitors such as pembrolizumab (anti-PD-1) and ipilimumab (anti-CTLA-4) exemplify this success, targeting immune checkpoints to rejuvenate exhausted T cells (Sharma et al., 2017). Clinical trials have demonstrated significant efficacy in melanoma, non-small cell lung cancer, and other malignancies (Garon et al., 2015). These therapies work by removing inhibitory signals, allowing cytotoxic T lymphocytes to target and eradicate tumor cells expressing neoantigens (Rizvi et al., 2015).

In addition, adoptive T cell therapy, including chimeric antigen receptor (CAR) T cells, exemplifies personalized immunotherapy where a patient's T cells are genetically modified ex vivo to recognize specific tumor antigens (Maude et al., 2014). This approach has shown remarkable success in hematologic malignancies such as acute lymphoblastic leukemia (Berge et al., 2020). These therapies depend on a detailed understanding of tumor immunology, antigen presentation, and immune regulation to optimize efficacy and safety.

Immunotherapy in Autoimmune Diseases

In autoimmune diseases, where the immune system erroneously attacks self-tissues, immunotherapy aims to restore immune tolerance. Strategies include the expansion of regulatory T cells (Tregs), which suppress autoreactive T cells, and cytokine modulation to shift immune responses from pro-inflammatory to anti-inflammatory profiles (Vasconcelos et al., 2018). For instance, low-dose interleukin-2 has been explored to selectively induce Tregs in conditions like type 1 diabetes and multiple sclerosis (Hartemann et al., 2013). Moreover, antigen-specific immunotherapy, such as oral or nasal delivery of autoantigens, attempts to induce peripheral tolerance and reduce pathogenic immune responses (Loladze et al., 2014).

Biologics targeting cytokines, such as anti-TNF agents in rheumatoid arthritis, have also exemplified successful modulation of immune pathways, providing relief from symptoms and halting disease progression (Klareskog et al., 2004). However, these approaches must balance immune suppression to avoid increased infection risks. The understanding of immune regulation at molecular and cellular levels continues to inform novel therapies for autoimmune diseases (Sakaguchi et al., 2010).

Conclusion

Immunotherapy exemplifies a paradigm shift in treating complex diseases by targeting fundamental immune mechanisms. Its success in oncology and autoimmune diseases highlights the importance of precise modulation of immune responses. Continued research into immune regulation, tumor microenvironment, and antigen specificity promises further advancements, potentially transforming outcomes for patients with previously incurable conditions.
