Recent Progress In Immunotherapy For Skin Cancer, Fadhli Aulia Mughni, Rinadewi Astriningrum, Aida Sd Hoemardani, Kusmarinah Bramono, Adhimukti T. Sampurna, Agassi Suseno Sutarjo

Journal of General - Procedural Dermatology & Venereology Indonesia

Skin cancer is a global health concern due to its growing incidence and high mortality rate. The most common therapeutic modalities in skin cancer include surgery, radiotherapy, and chemotherapy. However, those therapies do not specifically target cancer cells and may damage healthy tissues. Cancer induces immune response by releasing soluble antigens and danger signals caused by tumor cellular stress or death, while the immune system continuously monitor and control malignant proliferation through cancer immunoediting. Therefore, targeting this mechanism is a promising approach to manage cancer, especially those unresponsive to conventional therapies. Immunotherapy is a specific therapy that manipulates the immune …

Immune Gene Therapy Of Cancer, Hakan Akbulut

Turkish Journal of Medical Sciences

Cancer gene therapy emerged as a promising treatment modality 3 decades ago. However, the failure of the first gene therapy trials in cancer treatment has decreased its popularity. Likewise, immunotherapy has followed a similar course. While it was a popular and promising treatment with IL-2 and interferon and cancer vaccines in the 1980s, it later lost its popularity. Immunotherapy became one of the main options for cancer treatment with the successful use of immune checkpoint inhibitors in clinics approximately 10 years ago. The success of immunotherapy has increased even more with the introduction of cancer gene therapy methods in this …

Immunotherapy For Food Allergy: Myth Or Reality?, Gatot Soegiarto

Jurnal Penyakit Dalam Indonesia

Allergic reaction to food can have serious consequences. The only treatment option is strict allergen avoidance, but accidental ingestions happen frequently and can lead to severe and potentially life-threatening allergic reactions. Food allergy is one of the most common causes of anaphylactic reactions. Therefore self-injectable epinephrine should always be at hand in case of accidental exposure. Many food allergies may resolve over time, but most patients with persistent food allergies live with fear of anaphylactic reactions. Within the last several years, the usefulness of immunotherapy for food allergies has been investigated. Several food immunotherapies are being developed; which include oral, …

Evaluation Of Biological Response Modification And Immunotherapeutic Activities Of Barley-Derived Arabinoxylans Against Coccidiosis In Commercial Broilers, Masood Akhtar, Muteen Humayun, Zafar Iqbal, Mian Muhammad Awais, Muhammad Irfan Anwar

Turkish Journal of Veterinary & Animal Sciences

Plant-derived polysaccharides have been reported for diverse biological response modification (BRM) and immunotherapeutic (IT) activities in animals by activating their defense systems to perform better immunogenically against invading pathogens. Keeping this in view, this study was conducted to assess the BRM and IT activities of barley (Hordeum vulgare L.)-derived arabinoxylans (AXs) against coccidiosis in broilers. Significantly enhanced (P < 0.05) in vivo and in vitro lymphoproliferative responses to T-cell mitogens were revealed in broilers administered barley AXs when compared to the control group. Humoral immune response in terms of antibody titers against sheep erythrocytes was also found higher (P < 0.05) in AX-administered chickens. Furthermore, AX-administered chickens also showed higher weekly weight gains and improved feed conversion ratios as compared to controls. Results of the challenge experiment showed that the percentage of protection and daily weight gains were statistically higher (P < 0.05) whereas mean oocysts per gram of droppings and lesion scores were significantly lower (P < 0.05) in the chickens administered barley AXs as compared to controls. In conclusion, barley-derived AXs led to better growth performance and elicited humoral and cellular immune responses in commercial broilers that persisted against coccidial infection in broiler chickens.

Chemical Modulation Of Cancer Cells To Enhance Tumor Immunity, Florisela Herrejon Chavez

PSU McNair Scholars Online Journal

Breakthroughs in immunotherapy have led to cancer therapeutics that activate the immune system by blocking inhibitory mechanisms. This class of therapeutics has resulted in longer survival rates for cancer patients, some living over 10 years after being diagnosed as terminally ill. However, only a small fraction of patients who receive immunotherapy drugs respond favorably.Recent studies suggest that certain anticancer agents (both cytotoxic chemotherapeutics and targeted drugs) stimulate immune recognition of cancers. Identification of such immunomodulatory anticancer agents would make ideal partners for current immunotherapy treatments, thus increasing the proportion of the treated patients who benefit from immunotherapy. This study aimed …

Investigating The Role Of The Retinoblastoma Protein In The Expression Of Immunosuppressive Factors, Felipe Pérez Deliz, Pedro Santiago-Cardona, Phd, J. González, Phd, Jaileene Pérez-Morales, Meng

Journal of Health Disparities Research and Practice

Lung cancer remains one of the deadliest types of cancer, causing approximately 160,000 deaths per year in the US alone. Because of its poor detection techniques and highly invasive abilities, conventional treatments -such as radiation and chemotherapy- fail to improve long-term survival of patients. At the moment, the 5-year survival rate for all stages of lung cancer is only 16%. Recent breakthroughs in cancer research establish immunotherapy, which involves the stimulation of the immune system to target and attack cancer cells, as a highly promising alternative treatment against this deadly disease. However, the efficiency of this treatment varies on each …

Active Immunotherapy And Adoptive Cell Transfer As An Effective Cancer Treatment, Philip Jay Cynamon

The Science Journal of the Lander College of Arts and Sciences

There are many ways to fight cancer using the body’s own immune system. Some methods include the administration of vaccines while others involve stimulatory factors injected near tumors. One promising method is enlisting the help of T cells. To fight cancer effectively, T cells must be able to recognize cancerous antigens and the environment in which these T cells reside must be conducive to their function, survival, and proliferation. This paper discusses a method of providing such an environment called adoptive cell transfer, as well as the elements that effect this protocol and the ways in which the environment can …

Immunotherapy As A Treatment Option For Patients With Pancreatic Cancer, Yehuda Lehrfield

The Science Journal of the Lander College of Arts and Sciences

Pancreatic cancer is one of the worst forms of cancer that can develop in an individual. Traditionally, chemotherapy is administered but it has very limited success. Using the immune system to treat the cancer is very enticing and many studies have been conducted to attempt to harness the body’s own mechanisms to defeat the cancer. It seems that in order to properly treat the tumor a two pronged approach must be used. First, the immune system must be stimulated to react to the tumor and attack it. A possible cytokine that can be utilized is interferon alpha, which could result …
