CAR-NK (Chimeric Antigen Receptor Natural Killer) cells are making waves in cancer immunotherapy in recent years. To help researchers grasp this field, we used Stork's Big Analysis advanced feature to systematically review the trends, research hotspots, and core teams involved in CAR-NK research.

Go to Stork's Big Analysis page. Enter the keyword "CAR-NK," check "Analyze all authors in a paper," and click "Search," you can access the comprehensive analysis results.

Trend and Growth Rate  

Since 2014, the number of publications on CAR-NK has increased significantly, growing from sporadic reports to a robust area of study. In 2024, the number of papers reached 178, with an average annual growth rate of approximately 30%, indicating the rapid expansion and growing attention to CAR-NK cell research.

Country ranking

 Geographically, the United States leads with 327 publications, followed by China (236), Germany (89), Iran (54), and Italy (42). This distribution reflects both the early advantage of Western countries in cell therapy technology and significant progress made by Asian countries, particularly China.

Institute ranking

The University of Texas MD Anderson Cancer Center, Harvard Medical School, and Boston Children's Hospital are leading institutions in CAR-NK research.  If you're looking for collaborators or benchmarks, these are the hubs to watch. The analysis also ranks institutions based on the number of papers published and the total paper impact (publication count * journal impact factor).

Journal ranking

Most papers are published in journals like Frontiers in Immunology, Cancers, and Frontiers in Oncology. (Pro tip: Big Analysis even shows Days to Accept, so you can plan accordingly.)

Gene and Disease ranking

The data reveals the top targets for CAR-NK therapies: CD19 (by a wide margin), followed by CD38, CD7, CD70, and ERBB2. As for diseases, leukemia and multiple myeloma get the most attention, but solid tumors—like breast, lung, and colorectal cancers—are catching up.

Term frequency analysis

The importance of selecting appropriate target antigens is further underscored by the observation that the frequency of certain keywords–such as "chimeric antigen receptor",  "natural killer cells", and "CAR-NK cell therapy"–has steadily increased over time. This trend reflects a growing consensus among researchers regarding the potential benefits of harnessing NK cells as vehicles for targeted immunotherapy.

Author Network

The research community is closely connected, with major contributions from teams at the University of Texas MD Anderson Cancer Center. Chinese researchers are also playing a big role in advancing CAR-NK research.

This data offers a snapshot of where CAR-NK research stands and where it's heading. For researchers, this can help you:

· Stay on top of the latest trends in the field

· Identify potential collaborators

· Choose the right journals for your publications

AI Paper have made it easy for researchers to write papers. It can write structured drafts, including introductions, essays, abstracts, and now, discussion sections.

Now, AI Paper is getting even better! With an improved UI, more authoritative references, and better content alignment between sentences and cited references, this upgrade meets the demands of top-tier academic writing!

When completed, all references are automatically sorted alphabetically and displayed on the right side. Each reference comes with detailed information, including citation count, DOI, and PubMed ID. Clicking on any in-text citation will display full details on the right panel, allowing you to view abstracts or even access the full text.

AI Paper now also supports multiple citation formats such as APA, Harvard, and more. You can copy or download citation list.

Finding real references is easy for AI Paper – but as researchers, we want more: we want to cite the important references. That’s why this upgrade prioritizes references with high citation counts, those published in high-impact journals or the most recent studies, ensuring that the generated references are cutting-edge, credible, and academically valuable.

To make citation quality more transparent, each reference now displays its citation count in green at the bottom left. We can enter the PubMed ID of any reference into Citation Network (https://www.storkapp.cn/citenet/) to visualize both how it cites and is cited by other works.

In this network, each point is an article, arranged from left to right by publication date (the oldest is on the left). The size of the points is proportional to the number of times the article has been cited. As shown, Jiang et al. (2015) appears as the largest point, indicating its significant academic influence.

In addition to citing classic and authoritative papers, this upgrade also significantly increases the proportion of recent publications. In the following example, more than 50% of the references come from the past five years.

One of the most notable improvements in this upgrade is AI Paper’s enhanced citation accuracy. You may have already noticed that each reference now includes a “reason to cite”, ensuring that the selected references are highly relevant to the content.

For example, the referenced study by Reindl  (2018) is perfectly aligned with the cited content.

For example, if you enter details for a study titled “NIRS-Based Hyperscanning Reveals Increased Interpersonal Coherence in Superior Frontal Cortex during Cooperation”, and AI Paper will generate a discussion that

✅Summarizes key findings and explain which theories or perspectives they support.

✅Interprets the results, highlighting the study’s contributions.

✅Acknowledges limitations and propose future research directions.

✅  Wraps up with a concise conclusion.

With this upgrade, AI Paper is not just helping you write – it’s helping you think. From a cleaner UI to quality references and a structured discussion section, everything is designed to make your research writing smoother and more insightful.

Give it a try and see how it fits into your workflow. And of course—if you have any thoughts, feedback, or wild ideas for the next update, let us know!

Stork’s AI Paper is designed to generate high-quality introductions, essays, and abstracts based on the research title and any relevant materials. Some users have asked: Since the results from the Big Analysis are valuable for writing reviews, how can they be incorporated into AI Paper’s writing process?

To address this, AI Paper has provided a shortcut button allowing you to directly incorporate the data from Stork’s Big Analysis, including trends, growth rate, word frequency, genes, diseases, brain regions, etc.

In the example below, we enter the title “The development and application of hyperscanning” and added the Big Analysis results of “hyperscanning”. The language was set to Auto (matching the input language), references were set to Auto Search (no limits on reference range), and writing Capability/Speed was set to “better, slower” (for a more powerful model). Here are the Introduction written by AI Paper.

The generated introduction integrates the results from Big Analysis in several key areas:

AI Paper: 

Over the past two decades, there has been explosive growth in hyperscanning research. A recent bibliometric analysis encompassing 551 papers revealed that the number of publications using the keyword “hyperscanning” increased from a handful in the early 2000s to over 100 in 2024, reflecting a consistent annual growth rate of approximately 10%. This trend underscores both the scientific community’s growing interest in inter-brain synchronization and the technique’s expanding utility across various domains of neuroscience research. The increasing frequency of terms such as “neural”, “synchrony”, and “social” within these studies reflects the convergence of interests in understanding the neural basis of social interaction.
