Armando, I've just stumbled upon your videos. After watching only two, I've come to the realization that you will be the savior of my immunology grade. I offer you my deepest gratitude; thank you so very much for reminding me that immunology is not impossible to understand.
wow!!! thanks so much, Im studing VET. Im Mexican, and this videos really helped for my inmunology class, I really appreciate! KEEP IT UP! THANKS THANKS THANKS.
I remembered your channel from back in the days during my Bachelor. Happy that I remembered it now Im coming back to Immunology (+cancer) for a quick recap at the start of my PhD
u r the best itne short tym me itna kuch covr hojata hai... ur diagrsms are superb.. good handwritting... ur videos are very helpful plz make more videos of pharmacology.. and bacteriology..
my anatomy book says that eosinophil is the one that responds to an allergic reaction or a parasitic infection though? they lessen the severity of allergies by engulfing antibody-antigen complexes that reduce degree of inflammation and control its spread to adjacent tissues. Basophils migrate to an injury site where they discharge their granules into the interstitial fluids. Granule contains histamine which dilates blood vessels and heparin.
@Armando Hasudungan . Sir you have drawn 4 arrows under lymphoid progenitor cell does the fourth arrow suggest that dendritic cells come from lymphoid as well as myeloid progenitor? .. I am a big fan of your work. Keep up the good work. Thank you
Hi Armondo ...many many thanks for your excellent tutorial videos, is it possible to list the videos in the order they should be watched to make the step by step approach smoother. Thanks again.
I just did some more digging and realized that Dendritic Cells can be either Myeloid or Lymphoid in origin, but I still can't find anything about Mast Cells coming from Myeloblasts. Everything I can find says that Myeloid Progenitors branch into lineages that become Mast Cells, Granulocytes, and Megakaryocytes/Erythrocytes.
Actually i think that the haemopoetic stem cells are multipotent instead of pluripotent, because they give rise only to all types of blood cells, but not all types of cells in the body; they cannot become ,for instance, neuro cells..:?
Thanks for all of the videos and I'm a big fan. I found a diagram that seems to disagree with you, though, namely in that Myeloblasts precede only Monocytes and Granulocytes, excluding Mast Cells, which arise from a common precursor further "up" from a Myeloblast. It also says that Dendritic Cells arise from Lymphoid Progenitors, not Myeloid. I would include the link to the graphic, but RU-vid prevents me from doing so. Can you please reconcile these differences?
I learned that basophil is related to allergy reactions and secreting histamines as well, while eosinophils are more directed at the elimination of parasites
Aren't they both directed towards allergy reactions? The basophils along with mast cells release chemicals that attract eosinophil to the site of inflmmation (caused by the allergic reaction)?
Until now there is no certain answer, but the sources believe that coming in the stages of producing Basophils, cus they have the almost same function and similar morphology.
Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.
guys i need to have images of this. Is it possible to get them. it would really be nice to watch the videos and the check on the pictures just to review everything
My immune system is optimal, yet I have osteopenia. I do have a genetic predisposition for osteoporosis, but I’m wondering where the problem might lie in the the process. Any guidance in finding a biological explanation would be appreciated. Also NO pharmaceuticals taken, but many Ayurvedic and enzyme, as well as natural vitamin /mineral supplements, 150 minutes wily HIIT and tabata exercise. I am a medical student.Thank you 🙏
My teacher asked a question on the test about which one of these are NOT a leukocyte? The choices were erythrocytes, B cells, neutrophils, and dendritic cells. Is it just me or was this a poorly worded question bc when I picked red blood cells, unfortunately it was wrong!
yes, B cells are a kind of lymphocytes, and lymphocytes are a kind of leukocytes, but erythrocytes aren't leukocytes. WBCs= leukocytes RBCs=erythrocytes
Armando, the med symbol on your videos is wrong. The med symbol is actually a staff with one snake. The symbol on your videos is the one for accounting.
platelets are not molecules and are not „secreted” by a megakaryocyte! anyway, your videos are veryvery useful, but this was a huge mistake. keep posting these, i really appreciate them! j.
