Immune Checkpoint Discovery Has Implications for Treating Cancer and Autoimmune Diseases

Your immune system should ideally recognize and attack infectious invaders and cancerous cells. But the system requires safety mechanisms, or brakes, to keep it from damaging healthy cells. To do this, T cells—the immune system’s most powerful attackers—rely on immune “checkpoints” to turn immune activation down when they receive the right signal. While these interactions have been well studied, a research team supported in part by NIH has made an unexpected discovery into how a key immune checkpoint works, with potentially important implications for therapies designed to boost or dampen immune activity to treat cancer and autoimmune diseases.

How to efficiently search online databases for academic research

How to access academic databases

How to search academic databases, 1. use the campus network to access research databases, 2. find databases that are specifically related to your topic, 3. set up the search parameters within a database to be as narrow as possible, 4. ask a librarian for help, 5. slowly expand your search to get additional results, 6. use the pro features of the database, 7. try a more general database, if needed, 8. keep track of seminal works, frequently asked questions about searching online databases, related articles.

University libraries provide access to plenty of online academic databases that can yield good results when you use the right strategies. They are among the best sources to turn to when you need to find articles from scholarly journals, books, and other periodicals.

Searching an online research database is much like searching the internet, but the hits returned will be scholarly articles and other academic sources, depending on the subject. In this guide, we highlight 8 tips for searching academic databases.

• Use college and university library networks.
• Search subject-specific databases.
• Set up search parameters.
• Ask a librarian for help.
• Narrow or broaden your search, as needed.
• Use the pro features, where applicable.
• Try a more general database.
• Keep track of seminal works.

Tip: The best practice is to use the links provided on your library's website to access academic databases.

Most academic databases cannot be accessed for free. As authoritative resources, these multi-disciplinary databases are comprehensive collections of the current literature on a broad range of topics. Because they have a huge range of publications, public access is sometimes restricted.

College and university libraries pay for subscriptions to popular academic databases. As a student, staff, or faculty member, you can access these resources from home thanks to proxy connections.

➡️ Check out our list of EZProxy connections to see if your institution provides such a service.

Tip: Searching the right databases is key to finding the right academic journals.

Around 2.5 million articles are published EACH year. As a result, it's important to search the right database for the reference you need. Comprehensive databases often contain subject-specific resources and filters and these will help you narrow down your search results. Otherwise, you will have to screen too many unrelated papers that won't give you the reference you want.

Ask a librarian or check your library's A-Z resource list to find out which databases you can access. If you do not know where to start, you can check out the three biggest academic database providers:

➡️ Take a look at our compilations of research databases for computer science or healthcare .

Unlike in a Google search, typing in full sentences will not bring you satisfactory results. Some strategies for narrowing search parameters include:

• Narrowing your search terms in order to get the most pertinent information from the scholarly resources you are reviewing
• Narrowing results by filters like specific date range or source type
• Using more specific keywords

If your university library has a subject specialist in your field, you may want to contact them for guidance on keywords and other subject- and database-specific search strategies. Consider asking a librarian to meet you for a research consultation.

A specific search might not return as many results. This can be good because these results will most likely be current and applicable. If you do not get enough results, however, slowly expand the:

• type of journal

From there, you'll be able to find a wider variety of related technical reports, books, academic journals, and other potential results that you can use for your research.

Academic search engines and databases are getting smart! In the age of big data and text mining, many databases crunch millions of scientific papers to extract connections between them. Watch out for things like:

• related relevant articles
• similar academic resources
• list of "cited by" or "citations"
• list of references

When you have thoroughly finished searching a comprehensive database, you can move on to another to find more results. Some databases that cover the same topics might give you the same search results, but they might also cover an entire range of different journals or online resources.

You might prefer the search system of one database over another based on the results you get from keyword searches. One database might have more advanced search options than the other. You can also try a more general database like:

• Web Of Science

➡️ Visit our list of the best academic research databases .

There are experts in every field, people who have published a lot of scholarly content on your topic, people who get quoted or interviewed a lot and seem to be present almost everywhere. Pay attention to those names when searching a database and once you have found someone interesting, you can search for more from that person.

Also, take note of seminal articles, or those works that have been cited repeatedly within your field. Many major databases for academic journals have features that allow you to quickly determine which articles are cited most frequently.

Your institution's library provides access to plenty of online research databases. They are among the best sources to turn to when you need to find articles from scholarly journals and periodicals.

Searching the right databases is key to finding the right articles. Ask a librarian or check your library's website to access details. If you do not know where to start, check out the three biggest academic database providers:

Or take a look at our compilation of research database for computer science or healthcare .

You can narrow your search by only including articles within a specific date range or unchecking certain types of journals or magazines that are included in the database but have nothing to do with your topic. Make sure to also use very specific keywords when searching.

Unlike in a Google search, typing in full sentences will not bring you satisfactory results. There are different methods to search different databases. Ask a librarian or do an internet search on how to best search your particular database.

Narrowing down a search might not return many results. If you do not get enough results, slowly expand the date range, type of journal, or keywords.

Database Search

What is Database Search?

Harvard Library licenses hundreds of online databases, giving you access to academic and news articles, books, journals, primary sources, streaming media, and much more.

The contents of these databases are only partially included in HOLLIS. To make sure you're really seeing everything, you need to search in multiple places. Use Database Search to identify and connect to the best databases for your topic.

In addition to digital content, you will find specialized search engines used in specific scholarly domains.
