T cells are amazing white blood cells that play a crucial role in cell-mediated immunity. They can be divided into several categories - notably helper, cytotoxic, memory, regulatory, and natural killer (NK) - and their primary role within the immune system is to search out and destroy both invading pathogens and abnormal cells. Helper T cells also help to regulate the immune response.
The image above features a cytotoxic T cell, which destroy abnormal cells (most notably virally infected cells and tumour cells) and are also implicated in organ transplant rejection. Dendritic cells, pictured cyan blue in the photo, constitutively express high levels of both class I and class II MCH molecules - the type of receptor that cytotoxic T cells recognise - making them extraordinary potent activators capable of stimulating even “naive” T cells that have never encountered an antigen.

Haeng Bok Ha Gil Ba Rae (English Translation)
You turn your head and crying
I hate you being like this, that’s why I’m crying too
I’m missing you, missing you so much that I’m hurt
Hope you’ll be happy with my love even if I’m dead
Turn your head if you’re tired, I’ll be there
Because I left your tears behind
I left you first because I don’t want to see you alone…
Since now I can’t love you anymore
I’m missing you so much that I’m hurt
I hope you’ll be happy with my love even if I’m dead
I Hope you’ll be happy…hope you’ll be happy
(OST Sassy Girl Chun Hyang) liriknya sedih bener deh, pas nonton di youtube mata gue sampe berkaca-kaca gitu karena hampir mirip sama kondisi sekarang :(
