His sudden departure has left an irreplaceable void in the hearts of his colleagues, students, and the global rheumatology community.</p><p>Professor Danda's illustrious career was marked by his unwavering dedication to advancing rheumatology in India and the Asia-Pacific region and across the globe. His journey began with his graduation from the Jawaharlal Institute of Postgraduate Medical Education & Research, Puducherry, in 1985. He furthered his education with an MD in internal medicine from G.S.V.M. Medical College, Kanpur, in 1990 and a post-doctoral degree in clinical immunology from the Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, in 1995.</p><p>After advanced training in rheumatology in Adelaide, Australia, Professor Danda returned to India, where he joined the Christian Medical College (CMC), Vellore. There, he single-handedly established the Department of Clinical Immunology and Rheumatology, which has since grown to be one of the largest patient cohorts in the world. His vision led to the developing of a robust postgraduate education system at CMC, including the initiation of DM training in rheumatology and clinical immunology and a PhD program. His influence can be seen in the many faculty members at CMC who were his protégés.</p><p>Professor Danda's leadership extended beyond national borders. He served as President of the Indian Rheumatology Association (IRA) from 2017 to 2019. He held numerous roles within the Asia-Pacific League of Associations for Rheumatology (APLAR), including Editor-in-Chief of the International Journal of Rheumatic Diseases (IJRD), Treasurer, Vice President, and ultimately, President from 2021 to 2023. His dedication to rheumatology was recognized internationally, earning him numerous awards, including the Distinguished International Rheumatology Professional Award from the American College of Rheumatology (ACR) in 2023 (Figure 1-A).</p><p>A prolific author, Professor Danda published over 200 papers and delivered lectures at prestigious conferences worldwide. His research, particularly in the field of vasculitis, was not just significant, but truly groundbreaking. He led the APLAR Vasculitis Special Interest Group as Convener, advancing the diagnosis, education, and research of vasculitis, especially Takayasu arteritis, in the Asia-Pacific region (Figure 1-B). His establishment of the APLAR Academy and the Rheumatology Course for Physicians reflects his passion for education and his commitment to reducing disparities in rheumatology care.</p><p>Professor Danda was a brilliant scientist, visionary leader, and compassionate human being. He fought tirelessly against disparities in healthcare, ensuring that zonal and gender inequities were addressed within APLAR.

Bacterial permeability-increasing family member A1 (BPIFA1) exhibits anti-inflammatory properties; however, its impact on AR remains unclear.

Morphological assessments of nasal mucosal tissues were conducted. Levels of inflammatory mediators in nasal lavage fluid (NALF) and serum were quantified using enzyme-linked immunosorbent assay (ELISA) kits. Protein expressions of BPIFA1, phosphorylated and total p65 (p-p65/p65), and IκBα were evaluated through Western blot analysis.

We successfully developed a mouse model of AR, where BPIFA1 was similarly downregulated, indicating its possible involvement in modulating the NF-κB signaling pathway. Overexpression of BPIFA1 in this model attenuated inflammation and allergic responses by inhibiting the NF-κB pathway. Additionally, overexpression of BPIFA1 promoted the differentiation of regulatory T cells (Treg) and inhibited the differentiation of T helper 17 cells (Th17) in the NALF of AR mice, further demonstrating its regulatory impact on immune responses. The study confirmed that BPIFA1 upregulation reduced the levels of inflammatory cytokines TNF-α and IL-6, decreased infiltration of inflammatory cells, and modulated antigen-specific immunoglobulin levels and histamine in serum.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>BPIFA1 mitigated both inflammatory and allergic responses in AR mice induced by OVA through the modulation of the NF-κB signaling pathway and the balance between regulatory T cells (Treg) and T helper 17 cells (Th17).
