Background

CD4 is a glycoprotein expressed on the surface of certain immune cells, most notably helper T cells. It is a member of the immunoglobulin superfamily and has four immunoglobulin-like domains (D1 to D4). CD4 acts as a co-receptor with the T-cell receptor (TCR) to recognize antigens displayed by MHC class II molecules on antigen-presenting cells. The D1 domain of CD4 binds to the β2 region of MHC class II, bringing the TCR complex and CD4 into close proximity. This allows the tyrosine kinase Lck, bound to the cytoplasmic tail of CD4, to phosphorylate tyrosine residues on the cytoplasmic domains of CD3, amplifying the signal generated by the TCR. CD4 is also the primary receptor for the human immunodeficiency virus (HIV), and its interaction with the HIV gp120 protein is a key step in viral entry.

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

Great Gift for Young Coders
“Got this as a gift for a kid who’s starting to get curious about coding, and he really liked it. The visuals are clear, the instructions are easy to follow, and it breaks big programming ideas into fun, manageable steps. It’s not overwhelming, and it actually makes learning feel doable. Perfect for kids (or adults) who want to dip their toes into coding without getting lost in the jargon.” — Praying to the car gods
