Antigen-presenting cells display foreign antigens on the cell surface with the hopes of T cells noticing recognizing these complexes. The cells that do this on a routine basis are called Professional APC's. This group consists of dendritic cells, macrophages, B-cells, and certain activated epithelial cells.
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
Usually by size and the type of neurotransmistter it produces. Electrophysiologists also classify neurons by their firing ratesThis is an addition to the above-mentioned answer. To be more specific, we can classify neurons based on their structural or functional properties.1) Structural classification :based on polarity = unipolar + pseudounipolar + bipolar, + multipolar (Golgi 1, Golgi 2)based on their unique features (distinct shapes and locations) = basket cells + betz cells + medium spiny neurons + purkinje cells + pyramidal cells + Renshaw cells + granule cells + anterior horn cells2) Functional classification :based on directions = afferent + efferent + interneuronsbased on their actions on other neurons = excitatory (they increase firing rate) + inhibitory(they decrease firing rate) + modulatory (doesn't really related to firing rate, but they cause long-lasting effects)based on their discharging patterns = tonic or regular spiking + phasic or bursting + fast spikingbased on neurotransmitters they produced = cholinergic + GABAergic + glutamatergic + dopaminergic + serotonergic

The effect of dopamine on the cells of the GPi is to suppress them by preventing them from firing.
Karyotype
All nucleated cells bring pieces of endogenous proteins to the surface to display on the MHC protein.
all nucleated cells.
In Excel, you can set the column width to 2 and display borders around the cells of the number of cells you would like to display on your graph paper, then print.
It is configuring cells or ranges of cells to display some specific characteristic, like BOLD.
Enter =sum(A1:A20) in the cell that you would like to display the sum, where A1:A20 is the range of cells you would like to add.
Assuming you add more cells in series, the voltage will increase. If you don't change the resistance of the circuit, this in turn will also increase the current.
