Background

CD28, also known as the T-cell-specific surface glycoprotein CD28, is a protein encoded by the CD28 gene in humans. It is a glycoprotein that is constitutively expressed on both resting and activated T cells. CD28 plays a crucial role in T cell activation and signaling, providing essential co-stimulatory signals required for T cell activation, proliferation, and cytokine production. It enhances the production of IL4 and IL10 in T cells in conjunction with TCR/CD3 ligation and CD40L co-stimulation. CD28 interacts with its ligands, CD80 (B7-1) and CD86 (B7-2), which are expressed on antigen-presenting cells, to mediate the co-stimulatory signals necessary for T cell activation. This interaction is critical for the early events of T cell activation and the decision between immunity and anergy.

An amazing story by an amazing man! I am honored!
Format: Kindle
A must-have book for anyone of any age! Find out what happens on a snowy day for one adventurous little boy, who loves to play in the snow. The illustrations are unique and captivating, and blessed readers with the eclectic artwork and storytelling of Keats. This book is very special to me, as I was recently nominated for the 2015 Ezra Jack Keats Award for new author of the year. When I read this book, my heart swells with appreciation for the work of this man, and that I am even being considered for an award bearing his name. He was indeed a pioneer of children's books in his own right. I especially liked the chance at the end of the book, to get to read about and see how the book became the award winner that it is. His unique ability to transform words and art into captivating children's stories is phenomenal. I am grateful for his part in the paving of the literary road, so that new authors like me can use his works to continually inspire us to write from the heart, and through the loving, imaginative eyes of a child. If ever I feel doubtful in my own writing career, I will always read his books and remember that his name is synonymous with greatness. To even be considered for an award with his name on it, has indeed changed my life as a person and a writer. I hope my writing career will make him proud, that I was considered for his namesake award.

A Story to Melt Your Heart
Format: Paperback
This is an easy review to write, as there is nothing I dislike about "The Snowy Day." Although it was published in 1962, it is still as fresh and new as, well, newly-fallen snow. Keats knew how to tell a story well, in both words and through his beautiful and colorful images. It is a perfect children's book, because it is written from their point of view, imbued with their unalloyed sense of wonder and enchantment. Most importantly, I think, is that Keats' main character, Peter, is a little African-American boy, who lives in an urban setting. Peter is neither caricatured nor is he a symbol of or vehicle for speaking about social issues, which would have been very easy to do at the time it was written. Instead, it is a timeless story about a young child discovering snow for the first time and trying to understand its mysterious nature. Although Peter does not fully comprehend snow, he enjoys experiencing it just the same. In simple and direct prose, Keats captures and conveys what it is like to be very young and to encounter the beauty and mystery of the natural world, even in an urban setting. I plan to read this book to the younger children in my church's Sunday school...but it's really for me.
