Mechanism of spread of psoriasis:
Psoriasis is a condition characterized by an accelerated rate of basal cell division, which leads to the formation of thickened, red, scaly patches on the skin. If not properly treated, psoriasis can cause increased redness and swelling in the affected areas.
How does psoriasis occur?
Here's an explanation of how this happens:
1. Accelerated Cell Division:
In psoriasis, there is an abnormal immune response that triggers an overproduction of certain immune cells called T cells. These T cells mistakenly attack healthy skin cells, causing them to multiply rapidly. This accelerated cell division leads to the formation of thickened patches of skin known as plaques.
2. Inflammation:
The rapid turnover of skin cells in psoriasis leads to the accumulation of immature skin cells on the surface. These cells do not have enough time to mature and shed properly. The buildup of these cells, along with the ongoing immune response, results in inflammation within the affected areas. Inflammation can cause redness, swelling, and warmth in the skin.
3. Blood Vessel Expansion:
Psoriasis also triggers the expansion of blood vessels in the affected skin. This expansion, known as angiogenesis, contributes to the redness and inflammation seen in psoriatic plaques. The increased blood flow to the area can further exacerbate redness and swelling.
It's important to seek appropriate treatment for psoriasis to manage symptoms and prevent complications. Treatment options, as mentioned earlier, may include topical medications, phototherapy, or systemic medications depending on the severity of the condition. Working closely with a healthcare professional, such as a dermatologist, can help determine the most suitable treatment plan to reduce redness, swelling, and other symptoms associated with psoriasis.
