explain figure 2 please on the third page
In figure 2.A - shown that CD inhibit T-cell independent (without T cell), B cell activation. when B cell are culture with (PMact,IL-4 and IL-5) CD40-Ig at initial period, their is approximately 95 % inhibition is occur in IgG1 and IgM synthesis or poly clonal Ab production , but if CD40-Ig applied in 2 or 3 day of B cell culture then their is very less or no inhibitor effect is seen in both antibody production. While in control solution were CD40-Ig is absent their is normal production of poly clonal Ab from B cell through independent manner, due to the presence of PMactand (IL-4 and IL-5).
In figure 2B.Indicate CD-40 help B cell to active from fully intact T cell , IL-4 and IL-5 not from the radiation influence T cell. In control conditions were CD-40 Ig is absent and other are same conditions but their is decrease B cell proliferation is seen (negative control) because of distract T cell interaction.
So the Role of CD-40 Ig is to insure B cell activate through intact T cell only (T dependent activation only).

immunology practing samples and not sure if my answers correct. 1. NK cells are effective against viral infections because many virus infected cells a. are susceptible to lysis b. are susceptible to phagocytosis c. show reduced levels of MHC class I molecules d. show reduced levels of MHC class II molecules e. none of the above 2. Arachidonic acid serves as a substrate in the lipoxygenase and cyclooxygenase pathways resulting in the production of a. histamine, leukotrienes b. leukotrienes, prostaglandins...
Q 4. Explain how Fig.1A (arrow) result corroborates with the author hypothesis about Parkin aggresome and proteasome activity in PD? MG-132+ HMW 127- 84-- 41- DTT+ IP T HMW 6- IP : anti-flag WB: anti-ubiquitin Fia. 1. Parkin forms plexes A, HEK 293Tells transiently tranafected with FLAG-Parkin were divided into twe dishes and were either untreated or treated with 5PM MG-132 for 161). Cells were then lysed abidใหr-taining 1% Triton X-100 ลnd fractitated into "Iuble (S) and insoluble u) frac...
Please summarise the following content:(no word limit) EXPERIMENTAL PROCEDURES Animals All animals including pregnant ICR mice, neonatal Wistar rats, and NOD-SCID mice (8 weeks old, male) were purchased from CLEA Japan (Tokyo). All exper- imental procedures and protocols were approved by the Animal Care and Use Committee of Keio University and conformed to the National Institutes of Health Guide for the Care and Use of Laboratory Animals. Cells Mouse ESCs were obtained from the Laboratory of Pluripotent Cell Studies, RIKEN...
BELOW IS A METHOD. WHAT PROTOCOL (ALSO BELOW: A-F) MATCHES THIS METHOD? Method 5: Controlled ovarian stimulation and oocyte recovery was performed. Briefly, cycling females were subjected to follicular stimulation using twice-daily intramuscular injections of recombinant human FSH as well as concurrent treatment with Antide, a GnRH antagonist, for days 8-9. Unless indicated otherwise, all reagents were from Sigma-Aldrich and all hormones were from Ares Advanced Technologies Inc. Females received recombinant human luteinizing hormone on days 7-9 and recombinant...
1. The prevention of inflammatory immune responses to inhaled antigens in healthy individuals has mechanisms in common with those that prevent inflammatory immune responses to commensal microbes in the gut. One important component of immune regulation shared by these two situations is: a. The induction of increased numbers of IFN-g-producing T cells and ILCs in the airway and gastrointestinal epithelium b. The presence of tissue-resident mast cells that bind IgE through the high affinity IgE receptor c. The high levels...
For background: Q6= tyrosine kinase inhibitors & Q8= MHC molecules I need help with Q7 & Q9. I think Q7 is C but not sure. For Q9 I think it is phorbol myristate acetate since in my notes it says "Treatment of PMA and ionomycin on T cells can induce the effects of TCR stimulation" does this reasoning make sense? Although the (Q-6) approaches of CML treatment have dramatically changed the treatment of CML by inducing long term overall survival...
PLEASE COMPUTER TYPED* OR VERY CLEAR HANDWRITING with details 1. Radioactive (14C) uridine (lots of it) is added to a growing culture of bacteria for 10 seconds and then the drug rifamycin is added (rifamycin blocks the initiation of transcription, but not continued elongation of RNA polymerases that have already begun transcribing). At two-minute intervals, 1 ml samples are removed and placed on ice. The bacteria are lysed (broken open) and an enzyme is added that will chew up all...
1. You are studying phage transduction and trying to deliver a kanamycin resistance gene from one strain of bacteria to another using phage. The kanR gene is FAR away from the lambda prophage in your bacterium. Choose which type of transduction should you use for your experiment and explain why. a. lambda phage, specialized transduction b. lambda phage, conjugation C. T4 phage, generalized transduction d. A different phage with mitomycin C induction 2. A pig is infected with two subtypes...
lab question 1. What is the basis of the different purification methods? 2. What are some of the factors the might have interfered with your results? 3. How might you improve the process to increase the yield and purity? lab process E. coli BL21 (DE3) cells were transformed with the pET Topo-1521 vector containing a reading frame encoding the green fluorescent protein (GFP). Cells were cultured in M9ZB media at 37°C until the absorbance at 600 nm reached 0.7, at...
