Step-by-step explanation:

We have been investigating whether alloantigen-specific CD4(+)25+ regulatory T cells can be identified for use in treating graft-versus-host disease. CD150, which is upregulated on the surface of all activated T lymphocytes, was identified as a candidate marker for alloantigen-activated CD4(+)25+ regulatory T cells by gene chip analysis. Freshly isolated CD4(+)25+ cells had only low cell-surface expression of CD150, comparable to that of CD4(+)25- T cells. Increased CD150 expression was observed on all T cells after coculture with allogeneic stimulator cells. When purified CD4(+)25+ cells were precultured with allogeneic stimulator cells, then sorted into CD150+ and CD150- subsets, allosuppressive activity was contained primarily in the CD150+ fraction. These cells also suppressed the proliferation of alloantigen-activated autologous T cells, and they could be expanded in vitro without loss of their suppressive capacity. These results suggest that CD150 can be used as a marker for the identification of purified alloantigen-activated CD4(+)25+ regulatory T cells.

Answer:

4x cm.

Step-by-step explanation:

Suares have to have all 4 sides equal. The area of the rectangle (2x8) is 16.

16/4 = 4, so the square has sides of 4cm each to equal an are of 16. (4x4=16)

Which statements are true when using algebra tiles to solve the equation 8x + (–4) = 11x + 5?

kogti [31]

Answer:

See explanation

Step-by-step explanation:

You are given the equation $8x+(-4)=11x+5$

1. Add 8 negative x-tiles to both sides of the equation to create a zero pair on the left side. The equation then will have form

$8x+(-4)+(-8x)=11x+5+(-8x)\\ \\-4=3x+5$

2. Add 5 negative unit tiles to both sides of the equation to create a zero pair on the right side. The equation now is

$-4+(-5)=3x+5+(-5)\\ \\-9=3x$

3. Divide both sides by 3:

$\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3$

Finding Derivatives Implicity In Exercise,Find dy/dx implicity.<br> x2e - x + 2y2 - xy = 0

Klio2033 [76]

Answer:

the question is incomplete, the complete question is

"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . $x^{2}e^{-x}+2y^{2}-xy$ "

Answer : $\frac{dy}{dx}=\frac{y-(2-x)xe^{-x}}{(4y-x)}$

Step-by-step explanation:

From the expression $x^{2}e^{-x}+2y^{2}-xy$ " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.

we arrive at

$\frac{d}{dx}(x^{2}e^{-x )+\frac{d}{dx} (2y^{2})-\frac{d}{dx}xy=0\\$

for the expression $\frac{d}{dx}(x^{2}e^{-x})$ we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
