It simulates this hypersensitivity by making red things look bigger when you are wearing it.

当你佩戴头盔时，它会通过放大红色物体，来模拟这超敏反应。

Interestingly, there’s evidence that early exposure to allergens might protect against type 1 hypersensitivity.

有趣是，有研究表明：早期过敏原暴露将降低I型超敏反应发生率。

When tissues become damaged as a result of these immune complexes, it’s known as a type III hypersensitivity reaction.

免疫复合物导织损伤，称为III型过敏反应。

In this case, since IgE antibodies are being produced, this is an example of a Type 1 hypersensitivity reaction.

在这种情下，由于IgE抗体正在产生，这是I型超敏反应例子。

Alright, as a quick recap - allergic rhinitis is a type 1 hypersensitivity reaction which results in inflammation of eyes and nose.

得！简单回顾下：过敏性鼻炎是由I型超敏反应介导作用于眼部和鼻子炎症反应。

Allergic rhinitis is a type 1 hypersensitivity reaction, which is a type of allergic reaction that starts with exposure to an environmental allergen.

过敏性鼻炎属I型超敏反应，即由环境过敏原暴露所引起过敏反应。

These deposits and inflammation seem to be the cause of most of the symptoms of lupus, which remember is a type III hypersensitivity reaction.

这些沉积物和炎症是大多数狼疮症状原因，这过程称为III型过敏反应。

This is considered a type II hypersensitivity reaction, although it isn’t fully understood why some of these antibodies targeting specific cells and molecules develop.

这过程是II型过敏反应，目前尚不完全清楚这些攻击特定细胞和分子抗体产生机制。

Myasthenia gravis is a type II hypersensitivity disorder where the body produces antibodies that most commonly target nicotinic acetylcholine receptors on the surface of muscle cells.

重症肌无力是种II型超敏反应，身体产生抗体，常见靶点为肌肉细胞表面N胆碱受体抗体。

This is thought to be a type I or type IV hypersensitivity reaction, and is typically a response to a medication like NSAIDs, penicillin, and diuretics.

这被认为是I型或IV型超敏反应，通常来说，是对非甾体类抗炎药、青霉素和利尿剂等药物反应。

IgA nephropathy is therefore a type III hypersensitivity disorder, meaning that pathology and inflammation will happen at the site the immune complexes deposit, not where they are formed.

因此IgA肾病是种III型超敏反应，意味着病理和炎症反应会发生在免疫复合物沉积地方，而不是发生在免疫复合物形成地方。

The reason this happens is that in type 1 diabetes there is a type 4 hypersensitivity response or a cell-mediated immune response where a person’s own T cells attack the pancreas.

原因是在1型糖尿病中，有种IV型超敏反应，也叫细胞介导免疫反应，即人体自身T细胞攻击胰腺。
