Item Advancing Cancer Immunotherapy: The Potential of mRNA Vaccines As a Promising Therapeutic Approach(John Wiley and Sons Inc, 2023-10-04T00:00:00) Goyal, Falak; Chattopadhyay, Anandini; Navik, Umashanker; Jain, Aklank; Reddy, P. Hemachandra; Bhatti, Gurjit Kaur; Bhatti, Jasvinder SinghmRNA vaccines have long been recognized for their ability to induce robust immune responses. The discovery that mRNA vaccines may also contribute to antitumor immunity has made them a promising therapeutic approach against cancer. Recent advances in understanding of immune system are precious in developing therapeutic strategies that target pathways involved in tumor survival and progression, leading to the most reliable therapeutic strategies in cancer treatment history. Among all traditional cancer treatments, cancer immunotherapies are less toxic and more effective, even in advanced or recurrent stages of cancer. Recent advancements in genomics and machine learning algorithms give new insight into vaccine development. mRNA vaccines are designed to interfere with stimulator of interferon genes (STING) and tumor-infiltrating lymphocytes pathways, activating more CD8+ T-cells involved in destroying tumor cells and inhibiting tumor growth. A stronger immune response can be achieved by incorporating immunological adjuvants alongside mRNA. Nonformulated or vehicle-based mRNA vaccines, when combined with adjuvants, efficiently express tumor antigens through antigen-presenting cells and stimulate both innate and adaptive immune responses. Codelivery with additional immunotherapeutic agents, such as checkpoint inhibitors, further enhances the efficacy of mRNA vaccines. This article focuses on the current clinical approaches and challenges to consider when developing mRNA-based vaccine technology for cancer treatment. � 2023 Wiley-VCH GmbH.Item Protective role of natural products and bioactive compounds in multiple sclerosis(Elsevier, 2023-06-16T00:00:00) Bhatti, Gurjit Kaur; Singh, Harsh Vikram; Sharma, Eva; Sehrawat, Abhishek; Mishra, Jayapriya; Navik, Umashanker; Hemachandra Reddy, P.; Bhatti, Jasvinder SinghMultiple sclerosis (MS), a chronic multifactorial disease characterized by progressive demyelination and neurodegeneration, is rising rapidly in young adults. The pathology of the disease is not yet understood completely. However, neuroinflammation, oxidative stress, and hyperactive autoimmune response appear to play a prominent role in the pathogenesis of the disease. Several genetic, nongenetic, and environmental factors are also found associated with this autoimmune disorder. Although, it is still a matter of debate whether diet and lifestyle have an influence during the course of MS. Recent studies have highlighted several beneficial characteristics of natural bioactive compounds such as anti-inflammatory, antioxidative, immunomodulatory, and other neuroprotective effects, indicating their therapeutic potential to reduce the risk or ameliorate the progression of MS. Basically, these bioactive compounds are the chemicals found in minute amounts naturally in plants with peculiar health benefits. In this chapter, we have briefly described various natural bioactive compounds with neuroprotective effects against MS, including the polyphenols, vitamins supplementation, and natural products such as ginger, ashwagandha, and it seems that these compounds play a notable role in the treatment of MS. Further research is required to extend our understanding in developing more effective therapeutic strategies against the disease with lesser side effects. � 2023 Elsevier Inc.

Hemachandra; Bhatti, Jasvinder SinghAutophagy is essential in regulating the turnover of macromolecules via removing damaged organelles, misfolded proteins in various tissues, including liver, skeletal muscles, and adipose tissue to maintain the cellular homeostasis. In these tissues, a specific type of autophagy maintains the accumulation of lipid droplets which is directly related to obesity and the development of insulin resistance. It appears to play a protective role in a normal physiological environment by eliminating the invading pathogens, protein aggregates, and damaged organelles and generating energy and new building blocks by recycling the cellular components. Ageing is also a crucial modulator of autophagy process. During stress conditions involving nutrient deficiency, lipids excess, hypoxia etc., autophagy serves as a pro-survival mechanism by recycling the free amino acids to maintain the synthesis of proteins. The dysregulated autophagy has been found in several ageing associated diseases including type 2 diabetes (T2DM), cancer, and neurodegenerative disorders. So, targeting autophagy can be a promising therapeutic strategy against the progression to diabetes related complications. Our article provides a comprehensive outline of understanding of the autophagy process, including its types, mechanisms, regulation, and role in the pathophysiology of T2DM and related complications. We also explored the significance of autophagy in the homeostasis of ?-cells, insulin resistance (IR), clearance of protein aggregates such as islet amyloid polypeptide, and various insulin-sensitive tissues. This will further pave the way for developing novel therapeutic strategies for diabetes-related complications. � 2023 Elsevier B.V.Item Targeting Mitochondria as a Novel Disease-Modifying Therapeutic Strategy in Cancer(Springer Singapore, 2022-09-28T00:00:00) Bhatti, Gurjit Kaur; Pahwa, Paras; Gupta, Anshika; Sidhu, Inderpal Singh; Navik, Uma Shanker; Reddy, P. Hemachandra; Bhatti, Jasvinder SinghMitochondria are essential for the metabolism of energy, regulation of apoptosis, and cell signaling. Overproduction of reactive oxidation species (ROS) in mitochondria is one of the indications of cancer cells. Moreover, this boosts the proliferation of cancerous cells by causing genomic instability and altering gene expressions. Mitochondrial and nuclear DNA mutations caused by oxidative damage impair the mechanism of oxidative phosphorylation and can lead to more mitochondrial ROS output, genome instability, and cancer development. The classic approach to target mitochondria of cancerous cells with novel targeted therapeutics helps in targeting the mitochondrial apoptotic proteins and changing energy metabolism. A key benefit of selective drug delivery is that it reduces the drug�s toxicity and increases specificity. A better understanding of the mitochondrial role in tumor growth will help design more therapeutic agents with better selectivity. � Springer Nature Singapore Pte Ltd. 2022.Item Targeting Mitochondria as a Novel Disease-Modifying Therapeutic Strategy in Cancer(Springer Nature, 2022-01-31T00:00:00) Bhatti, Gurjit Kaur; Pahwa, Paras; Gupta, Anshika; Navik, Uma Shanker; Reddy, P.
