Have you ever seen or heard of a person who is allergic to bees get stung? Prescription medications can also cause an anaphylactic (life-threatening) allergic reaction by super-stimulating the immune system. The condition is rare and can be lethal, and is associated with medications such as Lamictal®, Tegretol®, anticonvulsants, and some antibiotics.

13 Patients experience the top layer of skin burning away and peeling off in sheets, accompanied by inflammation, swelling, painful blistering of mucous membrane tissues, and many other symptoms. For example, Stevens-Johnson Syndrome is a life-threatening immune system reaction that is caused by medication in 80% of cases. The effects of a supersensitized immune system, however, can be drastic and immediately observable. Immune suppression from prescription medication can go unnoticed until symptoms of lowered immunity, such as increased infections, begin to surface. This may create either a weakened or an overstimulated immune response. Long-term medication use can lead to a dysregulated immune system. Both of these conditions can contribute to or result in autoimmune and degenerative diseases. But the immune system can go awry, either not working efficiently enough, (weakened) or working too actively (super-elevated). The immune system is a highly complex set of mechanisms that are designed to kill pathogens and get rid of waste debris to keep the body healthy. Long-term medication is not always necessary, but frequently occurs without much consideration from the patient or the prescriber. Although pharmaceuticals can be relatively benign in controlled doses over limited spans of time, they can become detrimental when taken long-term. Unfortunately, not all side effects are minor. However, it is less common to discuss the downsides of frequent or long-term medication use, including side effects. After all, that’s exactly why we reach for medicine-we are confident, or at least hopeful that drugs can help us heal and become healthier, more vibrant versions of ourselves. Often, when we think of medication, whether prescription or over the counter, we focus solely on the positive, healing impacts manufacturers claim meds have on the body.
You can zoom in to see which bases are located at the kink site by converting them to CPK colors and spacefill model. Can you see why the DNA bends at this precise location? After a while, the protein will come back into view. Zoom in on the portion of the double helix that has a kink in it that causes the bend. Is the DNA still a straight molecule? What shape change can you see? Hide the LacI protein and look at the DNA's shape that is affected by LacI binding. What secondary structure reaches out to the other LacI protein? In which DNA groove do the LacI proteins bind the lacO promoter? You can click and drag to see the shape before clicking on the buttons below.Ĭonvert the proteins to cartoon shape and zoom in on the portions that allow the two LacI monomers to hold on to each other to make the homodimer.
This tutorial will highlight some of this repressor's structure and thus function. On this page, you can see two identical LacI proteins bound to each other and to the lacO promoter. LacI Baound to DNA 3D Structure of LacI Bound to lacO Promoter CPK Color Scheme
