I have seen multiple comments that stray away from how the immune system actually functions, so here is a brief overview. The immune system consist’s of two cells, T-Cells (cell mediated immunity) and B-Cells(humoral immunity). T-CELLS check the antigens(mainly a foreign substance, and can be a protein, nucleic acid, and some lipids and some larger polysaccharides) that are presented by a/the MHC protein(s) on a cell. [All cells have Class 1 MHC proteins, while (main two) Macrophages & Dendritic Cells and other WBC.] When presented, the MHC protein, with an antigen, binds to a T-Cell’s CD(Cluster Differentiation) Marker, thus creating the complex. There are different markers (CD3=all T-Cells, CD8= cytotoxic & suppressor T-Cells, CD4= Helper T-Cells.) If the T-CELL recognizes the antigen being presented, it will activate and produce THOUSANDS OF CYTOTOXIC T-CELLS(these attack and destroy infected/abnormal cells) & MEMORY T-CELLS(aren’t active, but they await a future need for an immune response.) B-CELLS follow a similar but slightly different pathway. B-Cells will first bind and intake an antigen. The antigen is then passed on to a CLASS 2 MHC PROTEIN, where it will return to the surface of the cell, these the cell is prepared/synthesized. The B-Cell will come in contact with a HELPER T-CELL, which will release/secrete Cytokines to induce B-CELL activation. Once activated, B-Cells begin to divide into Plasma Cells( which produce ANTIBODIES) & Memory B-Cells( standing by for future exposure). The ANTIBODIES produced here and made specifically for this antigen and can bind to the cell that began the response as well as other cells presenting the same antigen, rendering the antigen harmless. When you receive a vaccine, you are allowing your immune system’s cells to produce these MEMORY CELLS, thus cutting down the time for an immune response. Over time, if your body doesn’t encounter said antigens, it will begin to deplete these memory cells, as there is no need for them, thus the need for BOOSTER SHOTS. Coming I contact with the antigen contain the Corona Virus, isn’t hard, but giving your body a memorized state of alert is even easier.

2022.01.24 17:19 TKDMoi Ancient drop rate

What good does it do to level up shards if no ancients drop? I'm running t13 and gr70s and there's been 1- count 'em- 1 ancient that fits and 1 other. by not in other seasons I've seen many and usually filled my gear with ancients. yes would take longer to augment them since upgrading gems would take longer but at least I'd have ancients to do. So what is the drop rate anyway or is there some other way I should be looking for them. There's been surprisingly few rings to get to gheed so that's not a solution either.

2022.01.24 17:19 whaleforce9 Where to get wood in the US

Hey Friends. I just received an ooni koda 12 for Christmas. Im in the US in the southeast. I was wondering where everyone gets their woodsplits from for a reasonable price. Is there anywhere online you recommend purchasing? I found some wood splits that were a foot long that I cut in half, but hoping to just buy the right size in bulk somewhere. Thanks!
