Introduction to immunology

When we think of Immunology, we think of it as a specialised system developed to defend ourselves from external pathogens. However, it should be noted that our bodies' immune system should be seen as a tool, or a double edged sword.

The immune system's very basic function and objective is to protect the host from external pathogens. However, the body also tightly regulates the immune system, such that it does not end up harming ourselves instead.

One main example of immune system harming the host body, are autoimmune diseases (not going to be discussed in detail here). Yet, having an inefficient immune system (immunocompromised), increases the host's chances of opportunistic infections.

So in this blog, I will attempt to show the importance of maintaining that balance of the immune system, in order for our bodies to function normally in our everyday lives.

    I was diagnose April 17,2015 and find out I'm HIV positive.I was scared because there is no cure for HIV/AIDS but today some people still don't believe that there is cure for HIV, it can only be cured through Africans root and herbs,and our doctor's here in USA few of them know about the African herbal medicine can cure Hiv but they chooses to hide it from us just to make a sales of medical expertise. I did a research online finding way to get rid of my disease,I saw a comment about a herbal doctor on internet Name Dr itua ,who has cured several disease with his powerful herbal medicine, I contacted him on whats-app, chat with him explain my self to him.He said he can cure hiv perfectly well , he gave me his request which i send to him. within 5 days he sent me the herbal medicine through ups courier delivering service And told me how to take the medicine for 2 weeks to get cured,I did for 2 weeks, within this 7 days i notice a very big change in my health and i new some thing great has happened then i went to confirm my result after finishing the herbal medicine for two weeks it was absolutely negative.The doctor who new i was hiv positive was asking me how come i am negative, what did it took to get cure and were did i get this medicine from and how did i get rid of it I told him every thing about the herbal medicine that cure me. imagine doctor telling me not to let anyone know about it,I wasn't shock though i knew they know about the herbal cure but chose to hide it in other to make sales on medicals expertise,if you are HIV positive Or other disease such
    Cancer,Hiv,Herpes,Shingles, Hepatitis B,Liver Inflammatory,Diabetes,Fibroid,Parkinson's,Alzheimer’s disease.contact Dr Itua for any kind of herbal product and remedies through Email Or Website.. drituaherbalcenter@gmail.com www.drituaherbalcenter.com

Your skin is an 'armour'

When we usually talk about immunology, most of us think about white blood cells first. Recalling back to my previous post on the innate immune system, I stated that the innate immune cells are the front line of defence. However, let's not forget our epithelia. Skin Your skin is like an armour that protects your whole body from the environmental pathogens. It serves as a physical barrier, which blocks any pathogen from entering your system. The many layers of skin makes it much more difficult for any pathogen invasion. Also, in the epidermal layer, there are Langerhan's cells (epidermal dendritic cells) which will act to capture pathogens, and present it to T cells to activate them. Innate immune cells can be most commonly found in the skin, so that they are able to get rid of pathogen immediately. Now, the skin usually protects the whole body from external pathogens. However, there are 2 openings which can increase the chance of pathogen invasion. The mouth and nosetril...

Adaptive immunity

We are usually informed that, once we have had a certain infection, we are 'immuned' to the disease. But what exactly does it mean? Our bodies are very very smart. Our immune system, over millions of years of evolution, have developed very specialized cells, which can be 'educated' to recognise pathogens that we have encountered before. So with each exposure to a specific pathogen, adaptive immune cells will develop into specialized memory cells, which remembers that specific pathogen. Why is this function so important? With each exposure to a certain pathogen, the adaptive immune cells does not just remember that pathogen, it also develops cells which are very specific towards that pathogen, and it is also more efficient  in eliciting an inflammatory response to get rid of that pathogen.  Let's talk about the controversy of vaccines. It was pointed out that vaccines can cause autism in kids, but that is not the main point of this post. While I have not ...

Different immune cell types

So, let's branch into a little Haematology in this post. One of the main component of the immune system, are the immune cells (I usually like to imagine them as little troops of soldiers). Most of us know them as white blood cells. The flow chart above shows the different lineages of the various blood cell types, and to the left, we see the erythrocyte and megakaryocyte. Erythrocytes are basically the red blood cells, while megakaryocytes are the cells which produces platelets (thrombocytes), but we aren't going into details about that. So for immunology newbies, it may seem a little overwhelming, but its actually quite simple after going through it a few more times. As we can see, there are 2 main lineages from the multipotent haematopoietic stem cells: myeloid & lymphoid. In adaptive immunity, it is easy to remember that the small lymphocyte lineages (T and B lymphocytes), all belong to adaptive immunity. Apart from erythrocytes, megakaryocytes and small lym...
