Abeta  （β-amyloid）     (in English and Chinese 中英文)
 by: Joe Hing kwok Chu

β-amyloid, a starch like protein, is one of the anti-microbial peptides which are produced by the body to fight infection. They are small molecular weight proteins with broad spectrum antibiotic activity. They help getting rid of bacteria, viruses, and fungi.

Today, the different types of amyloids are re-name according to biochemistry. β-amyloid is being named as Abeta, where the first letter A represent amyloid.

Abeta is one of the antimicrobial peptides, part of the inate immune system,  known to be effective against  Candida albicans, Escherichia coli, Staphylococcus epidermidis, Streptococcus pneumoniae, Staphylococcus aureus, Listeria monocytogenes, Enterococcus faecalis, Streptococcus agalactiae, Pseudomonas aeruginosa, Streptococcus pyogenes, Streptococcus mitis, and Streptococcus salivarius. Abeta is especially effective against the fungus Candida albicans which causes yeast infection.

Abeta ( β-amyloid) plaques are precipitations protein lumps inside and outside the nerve cells caused by abnormal protein-protein interactions. These abnormal interactions of protein causes the dendrites of the nerve cells to be detached which form plagues. This plays a role in the dysfunction and death of nerve cells in diseases such as Alzheimer’s disease and Parkinson’s disease.

β-澱粉樣蛋白是抗微生物肽之一種。抗微生物肽是 身體為對抗感染而產生的 。他們都是小分子量的蛋白質具有廣譜抗菌活性。他們幫助身體消滅細菌， 病毒和真菌。
今天，不同類型的澱粉樣蛋白依照生物化學重新命名。 β-澱粉樣蛋白被命名為 Abeta。 其中第一個字母A代表澱粉樣蛋白 amyloid。

Aβ (β-澱粉樣蛋白)斑塊是蛋白沉 澱在神經細胞的 內部和外部。是異常的蛋白質的相互作用而形成的。常的蛋白質的相 互作用致 使神經細胞樹突斷落而造成 成了神經細胞功能障礙和死亡的疾病，如阿爾茨 海默氏病和帕金森氏病。

Aβ (β-澱粉樣蛋白) 是 抗菌肽之一。它對白色念珠菌，大腸桿菌，表皮葡 萄球菌，肺炎鏈球菌，金黃色葡萄球菌，李斯特菌，糞腸球菌，無乳鏈球菌 ，綠膿桿菌，化膿性鏈球菌，緩症鏈球菌，唾液鏈球菌有對抗作用。Aβ (β-澱 粉樣蛋白) 對抵抗白色念珠球菌特別有效。
