The NF-kB molecule is a transcription factor that controls the transcription of DNA for the perpetuation of the inflammatory immune response. It acts as a switch to turn inflammation on and off in the body. NF-kB has the ability to detect noxious stimuli, such as infectious agents, free radicals, and other cellular injuries, and then directs DNA to produce inflammatory cytokines. The NF-kB proteins are localized in the cytoplasm of the cell and are associated with a family of inhibitory proteins known as inhibitor of kB (IkB).[43,119] The TNF-α, and especially IL-1b, can also directly stimulate enzymes known as matrix metalloproteinases, which break down extracellular collagen matrix, a hallmark of inflammatory joint disease.[32,76,77] The IkB proteins are normally bound to NF-kB and block their nuclear localization signal. A variety of provoking stimuli can degrade the IkB and result in the nuclear translocation of NF-kB to be free to activate DNA synthesis of inflammatory cytokines [Figure 2].
Rubbing the pain relief cream on the affected area reduces the pain quickly. When you rubbing the cream or gel on the affected area then it warms the spot and increases the blood flow. The bodily action of massaging or rubbing allows the active ingredients to absorb into the affected skin smoothly. So you feel relaxed from severe pain such as back pain or knee pain.
NSAIDs don’t just damage your gut lining. They affect your gut bacteria, too. A study of regular users found that different NSAIDs caused different changes in gut bacteria. Ibuprofen and arthritis drug celecoxib (Celebrex), for example, increased pathogenic Enterobacteriaceae, a family of bacteria that includes E. coli, Salmonella, and a number of lesser-known bacteria that contribute to eye, skin, respiratory, and urinary tract infections.
