	'''Nickel allergy''' is a common cause of [[allergic contact dermatitis]], an inflammatory skin condition that occurs when the skin comes into contact with nickel-containing items. This type of allergy is prevalent worldwide and can cause significant discomfort and skin irritation.

	Nickel allergy is an immune-mediated response. When nickel ions penetrate the skin, they bind to skin proteins, modifying them in a way that the immune system recognizes as foreign. This triggers a type IV hypersensitivity reaction, mediated by [[T cells]]. Upon re-exposure to nickel, these sensitized T cells release inflammatory cytokines, leading to the symptoms of dermatitis.		Nickel allergy is an immune-mediated response.
