TRPV1 and TRPA1, are known to be functionally expressed in T cells, where these two channels differentially regulate effector immune responses. Telmisartan (TM), an anti-hypertension drug, has been recently repurposed to suppress various inflammatory responses. However, the possible involvement of TRP channels during TM-driven suppression of T cell...

There is no approved antiviral for the management of the Chikungunya virus (CHIKV). To develop an antiviral drug that can manage both CHIKV and arthritis induced by it, an ester conjugate of telmisartan (TM) and salicylic acid (SA) was synthesized (DDABT1). It showed higher potency (IC 50 of 14.53 μM) and a good selectivity index [(SI = CC 50 /IC 5...

Background Transient receptor potential ankyrin 1 (TRPA1) channels are known to be actively involved in various pathophysiological conditions, including neuronal inflammation, neuropathic pain, and various immunological responses. Heat shock protein 90 (Hsp90), a cytoplasmic molecular chaperone, is well-reported for various cellular and physiologic...

Toll like receptor 4 (TLR4), a pathogen-associated molecular pattern (PAMP) receptor, is known to exert inflammation in various cases of microbial infection, cancer and autoimmune disorders. However, any such involvement of TLR4 in Chikungunya virus (CHIKV) infection is yet to be explored. Accordingly, the role of TLR4 was investigated towards CHIK...

Transient receptor potential (TRP) channels are a superfamily of cation-specific permeable channels primarily conducting Ca²⁺ ions across various membranes of the cell. The perturbation of the Ca²⁺ homeostasis is the hallmark of viral infection. Viruses hijack the host cell Ca²⁺ signaling, employing tailored Ca²⁺ requirements via TRP channels to me...

The transient receptor potential vanilloid 1 (TRPV1) channel is a thermo-sensitive, polymodal cation channel. An increase in intracellular calcium (Ca2+) is essential for T-cell responses. Similarly, various immunosuppressive agents are also reported to induce Ca2+ influx. However, the possible involvement of TRPV1 during immunosuppression has not...

Chikungunya virus (CHIKV) has re-emerged as a global public health threat. The inflammatory pathways of RAS and PPAR-γ are usually involved in viral infections. Thus, Telmisartan (TM) with known capacity to block AT1 receptor and activate PPAR-γ, was investigated against CHIKV. The anti-CHIKV effect of TM was investigated in vitro (Vero, RAW 264.7...

An intracellular rise in calcium (Ca2+) is an essential requisite underlying T cell activation and its associated pro-inflammatory cytokine production. Transient receptor potential vanilloid channel (TRPV1) is a thermo-sensitive, polymodal gated and permeable to cations such as Ca2+. It has been reported that TRPV1 expression increases during T cel...
