Regulatory T cells (Treg) play important roles in suppressing immune responses and maintaining tolerance. Rabbit antithymocyte globulin (rATG) and horse ATG (hATG) are widely used in the treatment of immune-mediated syndromes, but their effects on Treg are unknown. We show here that in vitro culture of normal human peripheral blood mononuclear cells (PBMCs) with a low-dose rATG resulted in mark...

A rapid method for nearly quantitative isolation of human serum albumin is described. The present technic (1) is a modification of the Schwert method (2). In the present method 4 ml. of serum is precipitated with trichloroacetic acid in a final concentration of 5% (w/v). The precipitate is washed with TCA, and after aqueous suspension, ethanol is added to a final concentration of 80%. The undis...

Baby hamster kidney or HeLa cells form tumors in 100% of athymic nude mice. When such cells are persistently infected (PI) with RNA viruses, such as mumps or measles virus, the tumor cells either fail to grow or form circumscribed benign nodules. Neither the parental nor the virus PI tumor cells form invasive or metastatic lesions in nude mice. Previous studies have indicated a correlation betw...

Antibody to rat collagen, prepared in rabbits and injected into the circulation of normal or adjuvant-prepared rats, becomes fixed to its antigen and can then be identified in tissue sections under ultraviolet light by its fluorescence after application of fluorescein-conjugated anti-rabbit globulin. In heart, lung, liver, spleen, adrenal, kidney, jejunum, lymph node, thymus, joint synovia, per...

Skeletal muscle and liver tissue from 0,-day-old chick embryos were dissociated into separate cells using 0-25 % (w/v) crude trypsin. The effect of rabbit anti-actomyosin sera on the aggregation of these cells was estimated by the gyratory shaker and turbidimetric methods. Studies were also undertaken on the ability of fluorescein isothiocyanate-labelled rabbit anti-uterine actomyosin serum (FI...

Introductio n. Coronavirus infection is an acute viral disease with a predominant lesion of the upper respiratory tract caused by RNA-containing virus Coronaviridae family. However, it known that neutralizing antibodies play important role in antiviral therapy because they effectively inhibit reproduction viruses and reduce severity disease. Polyclonal contained convalescent plasma are usually ...

Twenty healthy 6-month-old male and female New Zealand rabbits with a mean body weight of 3.5±0.5 kg were fed a standard commercial rabbit diet and provided with water ad libitum containing 40 mg F/L for 70 days. Blood samples were obtained from each rabbit, and sera adenosine deaminase (ADA) activity and Creactive protein (CRP) and ceruloplasmin (CP) levels were determined with the following r...

Dear Editor, Anti-H antibody is a type of anti-red blood cell (RBC) antibody that agglutinates with H antigen, which is universally present on human RBCs. The most widely known problem related to the anti-H antibody is the potentially lethal hemolytic transfusion reaction seen in individuals with the Bombay O blood type [1-3]. Other anti-H antibodies are mostly found in A1 or A1B blood type ind...
