    NLRP3 Inflammasome in Autoinflammatory Diseases and Periodontitis Advance in the Management
    (Journal of Pharmacy and Bioallied Sciences, 2024) Hashim, Nada; Babiker, Rasha; Mohammed, Riham; Rehman, Mohammed Mustahsen; Chaitanya, Nallan CSK; Gobara, Bakri
    ct Inflammatory chemicals are released by the immune system in response to any perceived danger, including irritants and pathogenic organisms. The caspase activation and the response of inflammation are governed by inflammasomes, which are sensors and transmitters of the innate immune system. They have always been linked to swelling and pain. Research has mainly concentrated on the NOD‑like protein transmitter 3 (NLRP3) inflammasome. Interleukin (IL)‑1 and IL‑18 are pro‑inflammatory cytokines that are activated by the NOD‑like antibody protein receptor 3 (NLRP3), which controls innate immune responses. The NLRP3 inflammasome has been associated with gum disease and other autoimmune inflammatory diseases in several studies. Scientists’ discovery of IL‑1’s central role in the pathophysiology of numerous autoimmune disorders has increased public awareness of these conditions. The first disease to be connected with aberrant inflammasome activation was the autoinflammatory cryopyrin‑associated periodic syndrome (CAPS). Targeted therapeutics against IL‑1 have been delayed in development because their underlying reasons are poorly understood. The NLRP3 inflammasome has recently been related to higher production and activation in periodontitis. Multiple periodontal cell types are controlled by the NLRP3 inflammasome. To promote osteoclast genesis, the NLRP3 inflammasome either increases receptor‑activator of nuclear factor kappa beta ligand (RANKL) synthesis or decreases osteoclast‑promoting gene (OPG) levels. By boosting cytokines that promote inflammation in the periodontal ligament fibroblasts and triggering apoptosis in osteoblasts, the NLRP3 inflammasome regulates immune cell activity. These findings support further investigation into the NLRP3 inflammasome as a therapeutic target for the medical treatment of periodontitis. This article provides a short overview of the NLRP3 inflammatory proteins and discusses their role in the onset of autoinflammatory disorders (AIDs) and periodontitis.

    Natural Bioactive Compounds in the Management of Periodontal Diseases: A Comprehensive Review
    (Molecules, 2024) Hashim, Nada Tawfig; Babiker, Rasha; Rahman, MuhammedMustahsen; Mohamed, Riham; Priya , Sivan Padma; Chaitanya, Nallan CSK; Islam, Md Sofiqul; Gobara, Bakri
    Periodontal diseases, chronic inflammatory conditions affecting oral health, are primarily driven by microbial plaque biofilm and the body’s inflammatory response, leading to tissue damage and potential tooth loss. These diseases have significant physical, psychological, social, and economic impacts, necessitating effective management strategies that include early diagnosis, comprehensive treatment, and innovative therapeutic approaches. Recent advancements in biomanufacturing have facilitated the development of natural bioactive compounds, such as polyphenols, terpenoids, alka loids, saponins, and peptides, which exhibit antimicrobial, anti-inflammatory, and tissue regenerative properties. This review explores the biomanufacturing processes—microbial fermentation, plant cell cultures, and enzymatic synthesis—and their roles in producing these bioactive compounds for managing periodontal diseases. The integration of these natural compounds into periodontal therapy offers promising alternatives to traditional treatments, potentially overcoming issues like antibiotic resistance and the disruption of the natural microbiota, thereby improving patient outcomes.

    Highlighting the Effect of Pro‑inflammatory Mediators in the Pathogenesis of Periodontal Diseases and Alzheimer’s Disease
    (Journal of Pharmacy and Bioallied Sciences, 2024) Hashim, Nada; Babiker, Rasha; Mohammed, Riham; Chaitanya, Nallan CSK; Rahman, Muhammed M.; Gismalla, Bakri
    Alzheimer’s disease (AD) is a neurological condition that is much more common as people get older. It may start out early or late. Increased levels of pro‑inflammatory cytokines and microglial activation, both of which contribute to the central nervous system’s inflammatory state, are characteristics of AD. As opposed to this, periodontitis is a widespread oral infection brought on by Gram‑negative anaerobic bacteria. By releasing pro‑inflammatory cytokines into the systemic circulation, periodontitis can be classified as a “low‑grade systemic disease.” Periodontitis and AD are linked by inflammation, which is recognized to play a crucial part in both the disease processes. The current review sought to highlight the effects of pro‑inflammatory cytokines, which are released during periodontal and Alzheimer’s diseases in the pathophysiology of both conditions. It also addresses the puzzling relationship between AD and periodontitis, highlighting the etiology and potential ramifications.

    The Potential Role of Adipose-Derived Stem Cells in Regeneration of Peripheral Nerves
    (Neurology International, 2025) Mohan, Sunil P.; Priya, Sivan P.; Tawfig, Nada; Padmanabhan, Vivek; Babiker, Rasha; Palaniappan, Arunkumar; Prabhu, Srinivasan; Chaitanya, Nallan CSK; Rahman, Muhammed Mustahsen; Islam, MdSofiqul
    Peripheral nerve injuries are common complications in surgical and dental practices, often resulting in functional deficiencies and reduced quality of life. Current treatment choices, such as autografts, have limitations, including donor site morbidity and suboptimal outcomes. Adipose-derived stem cells (ADSCs) have shown assuring regenerative potential due to their accessibility, ease of harvesting and propagation, and multipotent properties. This review investigates the therapeutic potential of ADSCs in peripheral nerve regeneration, focusing on their use in bioengineered nerve conduits and supportive microenvironments. The analysis is constructed on published case reports, organized reviews, and clinical trials from Phase I to Phase III that investigate ADSCs in managing nerve injuries, emphasizing both peripheral and orofacial applications. The f indings highlight the advantages of ADSCs in promoting nerve regeneration, including their secretion of angiogenic and neurotrophic factors, support for cellular persistence, and supplementing scaffold-based tissue repair. The regenerative capabilities of ADSCs in peripheral nerve injuries offer a novel approach to augmenting nerve repair and functional recovery. The accessibility of adipose tissue and the minimally invasive nature of ADSC harvesting further encourage its prospective application as an autologous cell source in regenerative medicine. Future research is needed to ascertain standardized protocols and optimize clinical outcomes, paving the way for ADSCs to become a mainstay in nerve regeneration.

    Microbial Dynamics in Periodontal Regeneration: Understanding Microbiome Shifts and the Role of Antifouling and Bactericidal Materials: A Narrative Review
    (Current Issues in Molecular Biology, 2024) Hashim, Nada Tawfig; Babiker, Rasha; Priya, Sivan Padma; Mohammed, Riham; Chaitanya, Nallan CSK; Padmanabhan, Vivek; El Bahra, Shadi; Rahman, Muhammed Mustahsen; Gismalla, Bakri Gobara
    Periodontal regeneration is a multifaceted therapeutic approach to restore the tooth supporting structures lost due to periodontal diseases. This manuscript explores the intricate inter actions between regenerative therapies and the oral microbiome, emphasizing the critical role of microbial balance in achieving long-term success. While guided tissue regeneration (GTR), bone grafting, and soft tissue grafting offer promising outcomes in terms of tissue regeneration, these procedures can inadvertently alter the oral microbial ecosystem, potentially leading to dysbiosis or pathogenic recolonization. Different grafting materials, including autografts, allografts, xenografts, and alloplasts, influence microbial shifts, with variations in the healing timeline and microbial stabi lization. Biologics and antimicrobials, such as enamel matrix derivatives (EMD) and sub-antimicrobial dose doxycycline (SDD), play a key role in promoting microbial homeostasis by supporting tissue repair and reducing pathogenic bacteria. Emerging strategies, such as enzyme-based therapies and antifouling materials, aim to disrupt biofilm formation and enhance the effectiveness of periodontal treatments. Understanding these microbial dynamics is essential for optimizing regenerative ther apies and improving patient outcomes. The future of periodontal therapy lies in the development of advanced materials and strategies that not only restore lost tissues but also stabilize the oral microbiome, ultimately leading to long-term periodontal health.

    The Impact of Ozone on Periodontal Cell Line Viability and Function
    (Current Issues in Molecular Biology, 2025) Hashim, Nada Tawfig; Babiker, Rasha; Dasnadi, Shahistha Parveen; Islam, Md Sofiqul; Chaitanya, Nallan CSK; Mohammed, Riham; Farghal, Nancy Soliman; Gobara, Bakri; Rahman, Muhammed Mustahsen
    Periodontal diseases, including gingivitis and periodontitis, are chronic inflam matory conditions of the teeth’ supporting structures that can lead to progressive tissue destruction and loss if left untreated. Basic treatments like scaling and root planing, alone or combined with antimicrobial agents, are the standard of care. However, with the increas ing prevalence of antibiotic resistance and the need for new ideas in therapy, adjunctive treatments like ozone therapy have gained attention. Ozone (O3), a triatomic oxygen molecule, is used because of its strong antimicrobial, anti-inflammatory, and regenera tive activity and, hence, as a potential tool in periodontal therapy. This review of the use of ozone therapy in periodontal disease breaks down the multifaceted mechanism of ozone therapy, which includes the selective antimicrobial action against biofilm-associated pathogens, immunomodulatory effects on host cells, and stimulation of tissue repair. O3 therapy disrupts microbial biofilms, enhances immune cell function, and promotes healing by activating Nuclear Factor Erythroid 2-Related Factor 2 (Nrf2) and Mitogen-Activated Protein Kinase (MAPK) signaling pathways that regulate oxidative stress, inflammation, and apoptosis. Additional findings include its ability to upregulate growth factors and extracellular matrix proteins, which is significant for periodontal tissue regeneration. This review also discusses the application of O3 therapy in periodontal cell lines, emphasizing its impact on cell viability, proliferation, and differentiation. Advances in periodontal re generative techniques, combined with the antimicrobial and healing properties of O3, have demonstrated significant clinical benefits. Challenges, including the need for standardized dosages, effective delivery systems, and long-term studies, are also addressed to ensure safe and effective clinical integration. O3 therapy, with its dual antimicrobial and regenerative capabilities, offers an innovative adjunctive approach to periodontal treatment. Future research focusing on optimized protocols and evidence-based guidelines is essential to fully realize its potential in enhancing periodontal health and improving patient outcomes.
