B lymphocytes were first recognized in the bursa of Fabricius.

They actually do certain classes of T lymphocytes.

It's a subset of white blood cells called lymphocytes.

But the B lymphocytes frankly on some level well, I don't want to pick and choose favorites, but something in my brain I just really like the B lymphocytes.

You'll see that T lymphocytes participate in what's called the cell mediated response and we're going to do that in a future video.

Let's just talk about the humoral response right now, that deals with B lymphocytes.

Lymphocytes are another type of white blood cell or leukocyte.

But the main actors here are called lymphocytes, not to be confused with leukocytes because they still are

So B lymphocytes or B cells let me do them in blue.

T lymphocytes actually do start off in the bone marrow, but they mature and become what they are in the thymus.

So the B lymphocytes participate in what's called the humoral response.

Now lymphocytes can be divided into B lymphocytes, usually referred to as B cells and T lymphocytes.

At every stage, the incorrect instructions are passed along to the cells' offspring.

But when these lymphocytes, when these B cells are maturing, at one stage of their maturation or their development, there's intentional reshuffling of the

And this works for metastatic lymph nodes also.

Epidemiology The lymphoma is more common in the young and in males.

So let's say that that is a B lymphocyte.

However, magnetic resonance imaging has shown that when a person is undergoing an MS attack, the blood brain barrier has broken down in a section of the brain or spinal cord, allowing white blood cells called T lymphocytes to cross over and attack the myelin.

And just as the Tasmanian devil cancer is contagious through the spread of living cancer cells, so is this dog cancer.

It's a healthy response to the trauma, all of those immune cells rushing to the site of the injury to salvage cellular debris and prevent the spread of infection to elsewhere in the body.

These lymphomas show immunopositivity for ALK protein in 70 of cases.

We're made of cells and stuff between cells.

These cells out here, they're called podocytes.

It is very useful to diagnose the different types of leukemia and lymphoma.

It's surrounded like that by this structure, and these are cells here so you can imagine these are all cells over here.

So these were also biologically induced from that stem cell line.

Sentinel lymph node dissection has really changed the way that we manage breast cancer, melanoma.

Women used to get really debilitating surgeries to excise all of the axillary lymph nodes.

I edited out the last bit when I asked, Where is the neuron? and she says, The neuron?

Now both of these kinds of cells can make the place cells fire.

Several different translocations involving this gene have been identified in different cases of this lymphoma.

To determineeach stage, smaller categories must be defined first T. N. M. (tumor, lymph nodes, and metastasis).

So what that means is if the lymph node did not have cancer, the woman would be saved from having unnecessary surgery.
