硒（氨基酸硒Selenium Amino Acid Chelate、蛋氨酸硒Selenium Methionate）:強(qiáng)化人體免疫功能的微量元素

在人體內(nèi)，硒在淋巴結(jié)、肝臟和臟等組織、器官中的含量最高，且?guī)缀醮嬖谟谒械拿庖呒?xì)胞中，這有助于保護(hù)胸腺、淋巴細(xì)胞活性并促進(jìn)抗體形成。具體來(lái)說(shuō)，硒幫助人體增強(qiáng)免疫功能，主要體現(xiàn)在體液免疫、細(xì)胞免疫和非特異性免疫三方面。

抗體的產(chǎn)生是體液免疫的關(guān)鍵。硒元素能促進(jìn)免疫球蛋白（Ig）形成，提高漿細(xì)胞合成、分泌免疫球蛋白M(Ig M）和免疫球蛋白G(Ig G）等抗體的能力。實(shí)際研究顯示，對(duì)克山病區(qū)和大骨節(jié)病區(qū)（即嚴(yán)重缺硒地區(qū)）人群進(jìn)行免疫球蛋白測(cè)定后發(fā)現(xiàn)，病區(qū)人群Ig M和Ig G等含量顯著低于非病區(qū)，而在適量補(bǔ)充硒元素（氨基酸硒Selenium Amino Acid Chelate、蛋氨酸硒Selenium Methionate）后，病區(qū)人群體內(nèi)Ig含量明顯增多。

當(dāng)人體內(nèi)缺乏硒時(shí)，自身合成免疫球蛋白的功能會(huì)下降，T淋巴細(xì)胞的分化增殖能力也會(huì)下降。硒可通過(guò)GPX-4保護(hù)人體膜脂質(zhì)，防止其過(guò)氧化，且硒能提高脾臟細(xì)胞或血淋巴細(xì)胞對(duì)有絲分裂原刺激的轉(zhuǎn)化能力，進(jìn)而促進(jìn)免疫細(xì)胞增殖。

動(dòng)物實(shí)驗(yàn)結(jié)果顯缺乏硒可顯著抑制巨噬細(xì)胞殺傷微生物的能力，適當(dāng)補(bǔ)硒則可顯著提升巨噬細(xì)胞的吞噬活性。另有研究發(fā)現(xiàn)，硒（氨基酸硒Selenium Amino Acid Chelate、蛋氨酸硒Selenium Methionate）可通過(guò)GPX的抗示，氧化能力，保護(hù)巨噬細(xì)胞不被細(xì)胞內(nèi)的過(guò)氧化物傷害，從而提升巨細(xì)胞的吞噬能力。

Selenium (Selenium Amino Acid Chelate, Selenium Methionate): Trace elements that strengthen the human immune function

In the human body, selenium is found in the highest concentration in tissues and organs such as lymph nodes, liver and viscera, and is present in almost all immune cells, which helps protect the thymus and lymphocyte activity and promotes antibody formation. Specifically, selenium helps the human body enhance immune function, mainly in humoral immunity, cellular immunity and nonspecific immunity.

The production of antibodies is the key to humoral immunity. Selenium can promote the formation of immunoglobulins (Ig) and improve the ability of plasma cells to synthesize and secrete antibodies such as immunoglobulin M (Ig M) and immunoglobulin G (Ig G). Actual research shows that after measuring immunoglobulins in people in Keshan disease area and Kashin-Beck disease area (i.e., areas with severe selenium deficiency), it was found that the levels of Ig M and IgG in the disease area were significantly lower than those in non-disease areas. After appropriate supplementation of selenium (amino acid selenium Selenium Amino Acid Chelate, methionine selenium Selenium Methionate), the Ig content in the disease area increased significantly.

When the human body lacks selenium, the function of synthesizing immunoglobulins will decrease, and the differentiation and proliferation ability of T lymphocytes will also decrease. Selenium can protect human membrane lipids through GPX-4 to prevent peroxidation, and selenium can improve the transformation ability of spleen cells or blood lymphocytes to mitogen stimulation, thereby promoting the proliferation of immune cells.

Animal experimental results show that selenium deficiency can significantly inhibit the ability of macrophages to kill microorganisms, and appropriate selenium supplementation can significantly enhance the phagocytic activity of macrophages. Other studies have found that selenium (Selenium Amino Acid Chelate, Selenium Methionate) can protect macrophages from being damaged by intracellular peroxides through the antioxidant capacity of GPX, thereby enhancing the phagocytic ability of macrophages.
