Prize for "discoveries concerning the activation of innate immunity‚" is an especially fitting speaker for an entomology conference. He and his colleagues used insects‚ namely the fruit fly Drosophila‚ to decipher the potent antimicrobial defenses. Over many years‚ these studies have led to a general understanding of recognition of infection by flies‚ the connections between recognition and signaling‚ and the subsequent control of expression of immune responsive genes‚ namely of those encoding antimicrobial

Agammaglobulinemia 1. What are the differences between non-specific and specific (immunity) body defense? Non-specific defenses attack any foreign invaders by physical and chemical barriers first and then internally. Specific defenses are our immune system and the immune response that forgets specific invaders of the body that manage to get by the non-specific defenses. 2. In what tissue do B- and T- lymphocytes originate and what are the two steps involved in lymphocyte “maturation”? The precursors

that‚ as many females become susceptible during pregnancy‚ the hormone estrogen is involved in the etiopathogenesis (1). The etiopathogenesis of SLE is very complicated and involves a variety of factors such as genetics‚ environmental factors‚ and immune deficiencies. The genetic factors causing SLE is not entirely understood‚ although it is known that it is not a single gene contributing to SLE‚ but variations of many genes due to damages‚ improper splicing‚ deficiencies‚ and duplications. An individual

body and the shelter available. There are defence mechanisms in the body that fight against microbes such as: Passive immunity: This is the first defence system which tries to stop the pathogen entering the body. The body’s passive immunity systems include the skin which acts a physical barrier‚ mucus and cilia in the respiratory system which trap and move along bacteria‚ Hydrochloric acid in the stomach and enzymes (lysozyme) in tears

It is well known that Gliomas are amongst the most destructive types of cancers out there. Unfortunately‚ Gliomas are the most frequent tumors in the central nervous system accounting “for more than 32% of all primary brain and CNS tumors and 80% of all malignancies of the brain and CNS”. Tons of research has been done in this topic with a variety of different methods‚ however‚ it still has a poor prognosis with frequent recurrences. The gold standard so far to treat this type of tumors has been

Acne Vulgaris is a disease of the epidermal pilosebaceous follicles involving inflammatory and non-inflammatory clinical lesions in the skin. The multifactorial pathogenesis of acne includes sebum‚ ductal epidermal hyperproliferation‚ colonization of Proprionibacterium acnes and inflammation . Research has shown‚ P. acnes is not the cause of Acne Vulgaris‚ but is a significant contributing factor to the inflammation stage of this disease .

Erythematosus (SLE) is an autoimmune disease that composes many factors that contribute to the manisfestations of SLE. These factors include genetic and epigenetic regulation of gene expression‚ environmental factors‚ hormones‚ and a dysfunction in the immune system. It is estimated that about 1.5 million patients‚ and many other patients worldwide‚ have lupus. The survival rate of SLE patients improved from 50 % to 90% over the last 40 years from an estimated 5-year survival rate5. Managing SLE controls
